GREEN GUIDE PART TWO Heat Pump = 78gCO2 /kWh
So, a heat pump will give us some incredible savings. A 58% saving in CO2
over Gas, 68% saving in CO2 over Oil, 64% saving in CO2 over LPG, and 72% saving in CO2 over direct
electric! As most of the properties in the UK are on Gas, we can use a 60% saving in CO2
e each for
a heat pump over our current solutions. This means that we can take the 3.15tCO2
household was guilty of, and transform that into 1.26tCO2
to just 34 MtCO2
e per household (from 85 MtCO2 e for the entire UK).

There are obstacles and hurdles to overcome, but this is tried, tested and true technology. Gas, LPG or Oil can’t be made any less carbon intensive. It is what it is. With electricity, we have many more options and ways to be able to further reduce the carbon intensity. All in all, if we want to reduce the carbon footprint of our heating and hot water in the UK, we really need to be looking at heat pumps seriously.
Potential market
As of 2018, according to the ONS, there are around 27.6 millions households in the UK. The breakdown of which are as follows: Air source heat pumps are being installed at a rate of around 30,000 units per year. So, even if you take just the Oil and LPG households, and work on converting those properties from fossil fuels to heat pumps, there will be 50 years worth of work, on those 1.5 million properties alone.
The market will grow however, with new installers coming on board, so let’s assume
that we double the amount of installers / installations per year, and then let’s assume that over the next 10 years perhaps only 50% of the Oil and LPG properties are suitable for a heat pump whether that is for budgetary or practical reasons. This means we still have 12.5 years worth of work there, and that is before we move on to the solid fuel or direct electric properties. At 1.8 million households, direct electric on it’s own will prove to be a bigger market than both oil and LPG combined.
How easy is a heat pump to install? With the right support, they are no more difficult to install than a boiler. Granted, there are certain aspects of heat pump specification and selection which are a little more involved than some installation engineers may be used to, but the tools, training and support are out there. It’s just a case of selecting the right distributor who can make sure you are looked after from your first phone call through your first installation, and on. Some may wince at the simplicity of our (Freedom HP’s) installation diagrams, but
we believe they do their job well. There is no mistaking which component on the diagram is a 2 port valve or a circulation pump. A heat pump installation can be a daunting prospect for an installation engineer, so why make that life even more difficult? Below are the plumbing and electrical schematics for a full Samsung heating and hot water system. This is genuinely the most complicated an installation gets and aside from the field settings – which are no more difficult than you would see on a typical air conditioning install – we have it down to two pages.
Yes, there is a commissioning process, but if you follow our instructions step by step, you really can’t go wrong. In conclusion, air source heat pumps are a significant part of our domestic heating future. In order to make that future a reality, we need more good quality installation engineers on board. As an air conditioning engineer, you already have many of the skills that will make heat pumps a very straightforward addition to your current product portfolio.
