Finding the right heating solution for your business is key to keeping your fuel costs and carbon emissions low. If you are looking to make your business greener and cut your fuel costs, then a Renewable Hybrid system could be the option for you. In this section, you will be introduced to Gas Absorption Heat Pumps and Mini Combined Heat and Power units, and their benefits.
Gas absorption heat pump
How does it work?
A gas absorption heat pump (GAHP) extracts heat, like all heat pumps, from the air or ground and redirects it into the building it is trying to heat via a wet system of radiators.
The key difference from a conventional heat pump is that the GAHP is considerably more efficient. This is because it burns gas, instead of electricity to power its pump and the heat given off by the burning gas is captured and transferred into the heating system.
Benefits of using a GAHP
A typical air-source GAHP is capable of delivering efficiencies of around 130% while a ground-source version can deliver up to 150% efficiency with heat outputs ranging from c. 20kW to over 50kW per unit or more.
There are even hybrid units that incorporate a small condensing boiler, which triggers when outside temperatures fall below the heat pump’s normal operating parameters – thus ensuring that the heat pump can achieve peak output even in extreme temperature conditions.
Where it can be used
GAHPs are suitable for a broad range of commercial, industrial and residential buildings where there is a need for space heating and/or cooling and domestic hot water, such as:
- Industrial premises
- Leisure centres
- Care homes
- Commercial offices
- Super markets and shopping centres
Mini combined heat and power systems (MCHP)
MCHP is the on-site generation of electricity and the simultaneous capture of heat produced as a by-product of the generation process. CHP offers significant CO2 and energy cost reductions compared to conventional mains electricity and boiler heating.
MCHP units are ideally suited to situations where a business has a near, alll year round, 24 hours a day, 7 days per week, base-load requirement for heating space/domestic water and electricity requirement.
The classic examples being hotels or sports centre swimming pools, hospitals and hotels. Businesses that run day and night shifts are also ideal locations for MCHP.
