Hotels

Geyser Thermal Energy has solutions for hotels of all sizes from B&B’s to large global chains. The hotel industry has a very high hot water and cooling demand with millions of pounds being spent on energy and water in this sector every year. Through implementing heat recovery on air conditioning and chiller systems that energy that is paid for and usually expelled into the atmosphere can be captured and used to boiled hot water for use in the kitchens or bathrooms. This can then be topped up to meet higher demands by using a heat pump taking heat from various sources such as air, water or the ground which is a much more cost effective and efficient alternative to boiler systems.

The majority of hotels will use water softeners which are now becoming very expensive to run due to the amount of water they waste, amount of salt needed, cost of discharging waste water and maintenance demands and costs. Next Scale Stop is a proven alternative to water softeners without any of the limitations of use, they don’t waste any water or use any salts/ chemicals. It protects all your plumbing systems and equipment that encounters the incoming water from scale build up with up to 99.6% efficiency.

We offer advanced well water filters for swimming pools and Quantum Disinfection that removes the need for Chlorine in hot tubs and pools as it kills up to 99.99999% of bacteria in the water. These solutions are saving hotels thousands a year in costs through efficiency and low maintenance with Return on Investment (ROI) ranging from 1-5 years depending on the product and demands.

Restaurants/Pubs/Sports Clubs

Restaurants and pubs tend to have a constant hot water demand. Usually the hot water is provided by either a gas boiler or electricity (either a point of use electric water heater or immersion heaters).

All of this hot water demand could be met by using either heat recovery or a heat pump and in some cases both.

A heat recovery system could be used to get free hot water from;

  • Walk in chillers
  • Walk in freezers
  • Cellar coolers
  • Air Conditioning

If the restaurant/pub does not use any of the above, a Geyser RO indoor heat pump could be installed in the loft space or in the kitchen to provide very cheap hot water.

For space heating a larger Geyser heat pump can be used, even with existing standard radiators.  If the restaurant/pub has access to a water source it is ideal to use a Geyser water sourced heat pump for both heating and hot water.

Typically the payback for restaurants and pubs is 2-4 years, depending on the current set up. If the site uses electric immersion heaters or point of use water heaters the payback will be very good and can even be under 2 years.

Offices

Offices tend to have a very low hot water demand. However, the hot water demand is typically provided by electric immersion heaters or electric point of use heaters, both of which are very expensive to use.

This hot water demand could easily be met by using either a heat recovery from the Air Conditioning or even installing a Geyser RO indoor heat pump into a server room where it will provide hot water around 75% cheaper than electric heating and reduce the cost of cooling the server room.

Education

Educational facilities such as schools vary tremendously in their heating and hot water demand. We have surveyed a large amount of schools and without exception we have found several areas where their heating and hot water requirements could be improved. In fact the vast majority is wasting at least 30% of the energy they pay for and often the wastage is over 50%.

The Geyser RO indoor heat pump is perfect for school kitchens, they collect the excess hot air in the kitchen and use this energy to heat water, effectively providing the kitchens hot water demand for free.

Many schools use the same boiler for both their hot water as well as their heating. In winter this is fine as the majority of the demand on the boiler is the space heating. However, during warmer parts of the year there is no need for space heating the school is using an oversized boiler to provide a low hot water demand, resulting in very high energy wastage and unnecessary costs. When steam boilers are being used this wastage can be as high as 97%, i.e. 97% of the energy the school is paying for is wasted.  Using a heat pump to provide the hot water over the warmer months means that the large wasteful boilers can be turned off completely, changing the efficiency from 3% up to 400%.

Every school from primary schools to universities can benefit from using Next Scale Stop (NSS) as it prevents scale from building up on your pipes, boilers and sensors etc. Scale can have a dramatic effect on the efficiencies and the life span of your equipment. This can often lead to yearly costs rising by over 25%. NSS prevents this, protects your systems and is much more efficient and cost effect compared to alternative solutions such as Water Softeners.

Hospitals

Hospitals are one of the sectors that can benefit immensely from heat recovery. They tend to have large cooling systems, typically using air handling units and water chillers which provide cold water for the air handling units. Considerable energy can be recovered from these chillers and be used for hot water generation. Furthermore there tend to be various other cooling system which could also be used, such as;

  • MRI chillers
  • Direct cooling systems
  • Water chillers
  • Walk in fridges & freezers
  • Server & computer rooms

Even if the hospital has a combined heat and power (CHP) or is planning on one, installing heat recovery should be installed as it will reduce the energy consumption on site, not just provide it cheaper as a CHP does. Furthermore a CHP should be designed based on the minimum thermal base load and heat recovery reduces this base load. This reduces the size of CHP that is required, saving on both operating expense (CAPEX) and capital expenditure (OPEX).

Through our water disinfection products hospitals now have a viable and cheap solution to disinfecting surgical tools which is so critical for patient hygiene. The same type of system is perfect for the hydrotherapy pools, as it removes the need for chlorine and keeps the water clear and bacteria free. With the high water demands Next Scale Stop can be used in replacement of Water softeners which cost hospitals millions of pounds a year, this money can be used on more important things in the NHS.

Food & drink producers

The food and drink production sector is the optimum sector to be using heat recovery.

Constant cooling and refrigeration demands as well as a constant need for hot water make heat recovery a must for any food and drinks producer wishing to reduce their energy consumption. The heat recovery captures the energy from the cooling system and re-uses it to provide hot water. If even more hot water is required we can provide that by using large capacity heat pumps, removing the need for burning fossil fuels.

Areas where energy can be recovered from;

  • Air Conditioning
  • Process cooling
  • Water cooling
  • Warehouse cooling
  • Blast freezers
  • Ice machines
  • Foodstuff contaminated hot water

Areas where the recovered energy can be re-used;

  • Cleaning
  • Boiler and steam pre-heat
  • Potable hot water
  • Ice melting
  • Various processes
  • Space heating
  • Drying

Food and drink manufacturers have a lot of waste product that they have to dispose of normally by tankering it away at fairly high costs, Geyser Thermal Energy have solutions to try and reduce the amount of waste product by treating it through different filtration products. We can also recover the energy from the waste which can be re-used in the process to reduce costs further.

It’s important for food and drink producers to protect their systems from scale if they are situated in a hard water area, Next scale stop will protect the systems from build up of scale, leading to machinery lasting longer and needing less maintenance.

Take away Restaurants

Like restaurants and pubs, take away restaurants tend to have a constant hot water demand.  Usually the hot water is provided by either a gas boiler or electricity (either a point of use electric water heater or immersion heaters).

As take aways tend to have very little cooling demand, a small walk in fridge at the most, the best solution for them is to use the Geyser RO indoor heat pump. It can be installed in the kitchen, cooling and dehumidifying the air whilst at the same time provide a cheaper alternative to using fossil fuels for their hot water.

Typical payback for a take away is 3-4 years.

Bakeries

Bakeries are perfect for the Geyser RO indoor heat pump, much like commercial kitchens there is a lot of humid heat in the bakeries that can be used by the RO to provide the hot water needed. This can be boosted if chillers are used by utilising the heat recover unit on the chillers. Chillers work by extracting heat from inside the fridge and dumping it outside, so why not use this heat to reduce your hot water costs.

Listed buildings

Listed buildings are notoriously difficult when it comes to improving energy efficiencies and the renewable energy options available are very limited as solar panels and air source heat pumps typically don't fulfill the requirements of listed buildings.

We offer 3 different options for listed buildings;

  • Geyser RO indoor heat pump - Is designed to be installed inside the building in warm areas such kitchens and loft spaces.
  • Geyser water source heat pump - Can use any nearby water source to provide both heating and hot water.  The water source can be a lake, a river, a canal, a borehole and even the sea.  This heat pump also works as ground source heat pump.
  • Geyser heat recovery - If the site is using any cooling on site such as walk in fridges or freezers and/or air conditioning, using a heat recovery unit to recover energy from the cooling systems can provide some or all of the hot water requriements on site.

Leisure

Leisure centres and gyms tend to be very warm which means that air conditioning is typically always on, even in winter. The heat that the cooling system removes can be captured and re-used using heat recovery, providing thousands of litres of hot water every day.

Free hot water is only the beginning. Recovering the energy from the air conditioning will also reduce the energy consumption of the air conditioning system itself, increasing the savings even further. This means that typically we see a ROI of only 2-3 years for Leisure and sports complexes.

there are several options for leisure centres to reduce their water costs, they are:

  • Replace water softeners which have high running costs and waste a huge amount of water every year with Next Scale Stop which doesn’t use any salts or chemicals, it doesn’t waste any water and the media only needs changing every 3-5 years.
  • Next Well Water Filter is an advanced Sand Filter that uses high grade anthracite. This means it uses only half the amount of media, it retains double the amount of dirt and only requires half the amount of regeneration a normal sand filter does. Your original housing of the sand filter can all stay the same we just simply change the media inside of it.
  • Quantum Disinfection removes the need for Chlorine in pools and hot tubs. Through the silver and titanium media, electrons in the bacteria are drawn to them like a magnet which kills the bacteria with up to 99.999999% effectiveness. This has big cost savings due to not needing to replace the water as often nor having to re-heat the water.

Manufacturing

Energy:

Manufacturing varies considerably between sites and processes. Our broad knowledge along with various technologies means we can often identify areas where energy can be re-used within the manufacturing plant. Our designs are based on using equipment that can be retro fitted, ensuring minimal disruptions to operations and fast ROI’s

We can also help manufacturers with solutions for reducing their waste water by treating it with various filtration products, this will reduce costs of discharging water and/or tanking it away.

Thermal Energy for your business

A Variable & Controllable Cost

Thermal energy (space heating, refrigeration, air conditioning, steam, drying & hot water), is not an overhead nor a fixed cost. It is a variable and controllable cost. The cost of operating and maintaining thermal energy systems is based on a number of variables, such as energy cost & consumption, standing charges, carbon taxes, equipment and system efficiencies, climate, insulation, human behaviour and controls to name a few.

Focusing on only a part of your thermal system will only yield a small overall benefit if the other variables remain the same. Therefore it is essential to have a holistic view over all of the thermal systems on your site to ensure they are as efficient as possible. We will work with you to improve overall efficiencies and implement improvements that ensure minimum energy wastage, a reduction in reactive maintenance demands and ultimately save you money.
