System design and installation

Correct system design is of the upmost importance. The circulating water from a heat pump is typically 30 to 40 degrees lower than the circulating temperature of water from a gas boiler. For this reason it is often necessary to increase the size of some of your radiators to compensate.


In some rooms it might be as simple as exchanging single panel radiators for double radiators. In other rooms, it may be the case that the supply pipework (under the floor) that serves the radiator needs to be replaced with larger bore pipework.


We’ll take into account all of the necessary upgrade work in our quotation to you, to ensure that the finished system works as it should do.


At this point, we’d just like to make the following comment:


Quite a lot of consumers overly worry about the fact that heat pumps send water out to the heating system at a lower temperature than their gas boiler. A very similar thing happened in the early 2000’s when condensing boilers became mainstream. Condensing boilers circulate water at a lower temperature than the old-fashioned traditional boilers. At worst, if the then installer felt necessary, a few radiators were increased in size as a part of the installation, to ensure a satisfactory end result.


This is exactly the same principle.


There will also be an unvented hot water cylinder fitted as a part of the installation. This will often be sited in the loft space, or within an existing airing cupboard.


Once we have completed a proposed system design for you, we are perfectly happy to discuss any aspect of the design with you, before leaving you in peace to consider your quotation.
