False – Heat pumps will work down to around -20C

False – Heat pumps work with radiators and UFH

False – Heat pumps can maintain internal temperatures like 21C just like a boiler can.

False. They do make noise but they are quieter than an old oil boiler burning. Manufacturers have worked tirelessly on noise reduction and you’ll be pleasantly surprised how quiet they are.

True – Ground source heat pumps are more efficient than air source due to the higher temperatures underground in the colder months (Heating season).

False – Heat pumps work perfectly well in existing homes provided they are designed and installed correctly.

True – That is the maximum energy a boiler can extract from a burning fuel process.

True – GSHP can actually be more than this and ASHP normally achieve around 300%. This means for every KW they use in electric they produce 3-5 KW in heat .

False – Heat pumps need plenty of air flow to work efficiently and must be placed outside with good air flow!

False – Heat pumps do not need to be sited on a south facing wall.

True – The expected life span of a heat pump is longer than a boiler and manufacturers state 10-15 years for ASHP and 15-20 for GSHP

True – Just about the whole of Sweden is heated using heat pumps. So you can be confident that if they work in the Swedish climate they will certainly work in the UK.

True – The new NIBE S-Line range now makes this possible. The S-line controller can interrogate a PV inverter and direct the power where needed in the system. Smart!!

False – The system is weather compensated. This means the rads will feel warmest to touch on the coldest of days. They wont however feel as hot as they did before to touch if you had a boiler and we don’t encourage touching rads to assess if the heating is on. The stat/control temp and your comfort tell will tell you that.

True – GSHP’s do require a lot of outdoor space. The older the house. The more space is needed. Normally at least twice the size of the homes footprint.

True – In most cases yes we would look to remove those and move you over to a pressurised system with no roof tanks.

True – You will get this as part of the package which means better showers and hot water performance in most cases.

True – We were very early advocates of heat pump technology and have hundreds of installations across Norfolk.

True – Heat pumps need servicing every year but costs are similar to oil boiler servicing.
