Six reasons not to buy a heat pump
2. They heat houses more slowly
Currently, heat pumps can be slower to heat a house than a traditional boiler. Traditional central heating systems heat water by burning gas that can bring radiators to around 75 ° C. Hydrogen boilers will work in a similar way once they are widely used.
Heat pumps only heat water to a maximum of around 65 ° C, which means houses that use them take longer to warm up.
3. Better models will be available in the near future
Around 32,000 heat pumps were sold in the UK last year, well below the government’s target of 600,000, and a tiny amount compared to the 1.6 million gas boilers installed over the same period, according to Boiler Guide.
In an interview with The Telegraph, Economics and Energy Minister Kwasi Kwarteng admitted that gas boilers “have been refined over many years … heat pumps are still in their infancy”.
Since the number of heat pumps installed annually will increase in the coming years, significant price reductions for the devices can be expected.
As new models develop, more efficient devices are likely to become available in the market.
This means that households that opt for a heat pump now run the risk of jumping the gun and missing out on a cheaper, more efficient and more effective device in a few years’ time.
4. They may not work in your home
Almost all houses can accommodate an air source heat pump, but a geothermal device requires more land.
However, not all homes will be compatible with air-to-water heat pumps as the units will usually have to stand outside on the ground to work. This can be a problem for those who live in townhouses where outdoor space can be limited.
The required interior space for the devices may also be lacking in small apartments, as large hot water storage tanks are required.
In some cases, they can be wall-mounted, but must be in an accessible location for settings to be adjusted.
Air source heat pumps also make some noise when working, especially in cold weather.
David Holmes of Boiler Guide said, “The important point is that an air source heat pump for the right property can be an effective low carbon heating system.
“With so many ‘ifs and’ buts’ related to technology, there is no one-size-fits-all solution as to how we will heat houses in the future.”
