UK HEAT PUMPS MARKET ALMOST GUARANTEED
In many European countries, heat pumps have been an accepted system and technology for between 20 and 30 years and statistics are more easily available than in the UK where they are virtually non-existent. That’s the view in a new report on the generic heat pumps market. The government’s target of 15% of energy to be derived from renewables by 2020 assumes significant growth of ground and air source heat pumps in order to meet this commitment. The market value for both ground and air source heat pumps in the residential, commercial, public and industrial sectors is forecast at more than £50m in 2010 which, when added to installation costs of about £13m, gives an overall estimate of around £65m.
A further breakdown of the value by sector is detailed in the report. Despite wide acceptance in some European markets, volume production is still relatively low. Most leading players are parts of major groups involved in the heating industry, with international operations.
In the medium term, capacity will need to increase both in terms of production and installation capacity which could be a significant issue for other renewable technologies as well as heat pumps. In addition, there will almost certainly be a requirement to improve the technology as the market matures.
Some targets are as high as 1 million installations by 2010 but these targets are ambitious and will require significant government funding support to achieve. There are a number of barriers to the growth of heat pumps in the UK including: investment costs; installation costs; ease of installation; long pay-back period; performance in poorly insulated homes; limitations for systems with standard radiators and for water heating; competition in off-gas areas from other sustainable technologies; and they are also less suitable in retro-fit applications. Given the outcome of the election and the objectives of reducing public spending, the actual commitment levels will undoubtedly become clearer during the rest of 2010 as spending plans are announced.

The Government’s increasing desire for high energy efficiency standards is likely to get tougher every few years. This is good news for heat pumps and for the industry. Quality and service together with innovation remains the key to the market continual growth. Everything else seems to be working in its favour.
The Heatinverter from Fairlocks uses a rectifier to convert the incoming AC current to DC and then uses pulse-width modulation of the DC current within an inverter (electrical) to produce AC current of a desired frequency. As the speed of a brushless motor is synchronised to the frequency of the AC current it is thus possible for the Heatinverter compressor to be run at different speeds. A microcontroller then samples the ambient air temperature and adjusts the speed of the compressor appropriately. The effect of eliminating stop-start cycles is to increase efficiency, extend the life of components, and eliminate sharp fluctuations in the load the heat pump places on the power supply. This reduces the demand on the compressor which in turn reduces the running cost and improves efficiency.
The ‘Heatinverter’ range from Fairlocks operate down to an ambient air temperature of 0°C, with sizes from 12 – 30kW.
Every one unit of energy put into a Calorex heat pump will produce five units of energy at the right conditions, meaning that the cost of heating a pool with a heat pump is much lower than with other forms of heating. Quiet in operation, they are fully automatic and require minimal maintenance.
Summer season models will successfully heat the pool water throughout a typical UK summer season, operating when outside air temperatures exceed 7°C.
The reverse cycle range, with a more comprehensive design, offers an extended season usage (April to October is typical). This range can continue to operate even when the outside air temperature is below 0°C.
Occasionally, an all-year swimming season is preferred, which also applies to most indoor pools, and these are called Extended Season models. spn
