PUMPS, WASTE MANAGEMENT & WATER TREATMENT BSEE A Place for Pumps


It has become clear over the last few months that a mix of technology will be required to help decarbonise the way we heat our buildings and provide hot water to our homes. This was cemented by both the Prime Minister’s 10point plan and the subsequent Energy White Paper which both outlined concrete steps to how we reach our net zero goal by 2050.


O ne such


technology is heat pumps. In his plan the Prime Minister


announced a


target to install 600,000 heat pumps every year by 2028. Looking more closely, we can certainly see how 600,000 may be at best ambitious and perhaps even unrealistic, but a large increase in Heatpump take-up is certainly likely – particularly in certain sectors.


Enter new builds Heat pumps would certainly be well-


suited for new-build homes. The property can be specified and built with heat pumps in mind at the outset. So space can be provided for a hot water cylinder and sometimes a buffer tank which are required in a heat pump-powered heating system. Also, radiators and pipework can be specified and fitted at the correct sizing and material to support an efficient heat pump.


This has certainly been confirmed by the recently published second consultation to the building regulations. Within this, the Future Home Standard has been put together in such a way that makes it almost impossible to fit a fossil-fuelled heating source into new builds from 2025 onwards. This means that heat pumps will certainly be the way forward for this area, which is a comforting reassurance for manufacturers of the technology. With this boost we should see an expansion of the market for new- build, taking us into the margin of 200,000 a year, which is a big step up.

Time to train


With this knowledge, the heating industry can start to put the infrastructure into place for the implementation of heat pumps. We


can gear ourselves up to training and recruiting staff on heat pumps ahead of the inevitable uptake in sales. Training is one of the most important parts, not just for manufacturing and engineering, but most importantly for installers themselves, who will be on the frontline when it comes to putting the heat pumps in. New low carbon training is already being looked at for the near future, an opportunity for installers to get to know the technology that is most likely going to be heating our homes in years and in some cases decades to come. For heat pump training this will have other benefits in terms of giving installers the know-how to work with


hybrid systems. There is talk around hydrogen hybrid systems for existing homes, where a heat pump is backed up by a hydrogen-fired boiler which only kicks in when the temperature is too low for the heat pump to effectively warm the home. This would help future-proof home heating even more, for on the off- chance hydrogen doesn’t come along (which given early indicators seems unlikely) the house’s carbon usage or creation is still reduced by the heat pump.


What is known for certain, though is that heat pumps will play a strong part in getting at least new build homes as close to, if not completely, zero carbon.
