Energy and Home Heating
YES – it is getting more complicated and there are things you need to know ……
WHY – to keep those bills down and to help lower our impact on the planet
With so much conflicting information on the news and increasing ‘hard hitting’ sales pressures on everyone, we thought we would try and bring some good information together:
1 – How Heat Pumps Work
2 – Costs & Savings
3 – Solar – Solar Thermal and Solar PV (yes … there are two types)
4 – Other Considerations
Or ………….. you can call in to our showroom and see what it is all about.
1 – How Heat Pumps Work:
A heat pump operates like a fridge in reverse, taking the available heat from the ground or the air surrounding a property and using that to add warmth to your home.
Heat pumps use heat exchangers and compressors to take heat from the outside air or the ground and maximize the heat gain available.
For example you may have noticed that a bicycle pump, gets warm when it is used, the gasses in a heat pump experience the same temperature rise due to compression.
2- Costs and Savings

3- Solar Thermal & Solar PV
Solar thermal panels heat liquid, which is then passed through heat exchangers to heat a hot water tank (Called a Heat Store / Buffer Tank or Accumulator). This hot water tank can then run a heating and hot water system. Because the tank is so well insulated, hot water created during the day is also available at night.
Solar PV panels provide electricity. This has historically been sent back into the National Grid providing ‘pay-back’ at the current ‘feed-n tariff’.
However new battery technology is now allowing homes to store the electricity their panels produce for use ‘on-demand- when required. This technology will remove the dependency on connection to the National Grid and allow homes to benefit from the full value of the electricity they generate. A smart controller such as the Regulus IR12 can utilise battery storage generated from sunlight or wind, together with other potential energy sources to create managed energy independence.
4- Other Considerations
- Controller – The controller used with modern heating systems is one of the most important decisions, now and in the future. A controller has to properly manage different potential heat sources ad multiple zones within the home. It may have to manage underfloor heating, radiators and hot water. In addition the home owner and their heating service engineers may want to manage this on-line. Controllers such as the Regulus IR12 represent this new generation of controllers.
- Noise – Some heat pumps, especially small ones can be noisy. Noise, reliability and economy are some of the criteria we use to assess heat pumps.
- Size – Small heat pumps need to operate at higher speeds and stretch manufacturing tolerances. We recommend heat pumps that are tried and tested to work in all conditions.
- Air Conditioning Units – Working with similar technology, some heat pumps are derived from existing air conditioning units. We recommend Heat Pumps which are designed to be Heat Pumps, not air conditioning units.
- Multi Energy – without doubt homes in the future will have multi energy sources of heating, driven by a number of factors. Ashburn are specialists in multi energy systems – http://ashburnheating.co.uk/hot-stuff-multi-energy-heat-bank/
