SPN APR 2011 HeatPumps HEAT PUMPS MARKET ALMOST GUARANTEED


Last year, a report on the generic heat pumps market was produced by AMA Research entitled ‘Renewable Energy – Ground and Air Source Heat Pump Market – UK 2010-2014’. According to the report, 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 all sectors was expected to be more than £50m in 2010 plus further installation costs of about £13m.


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.


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.


The Heatinverter 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. The speed of a brushless motor is synchronised to the frequency of the AC current making it 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 air-conditioner places on the power supply. This reduces the demand on the compressor which in turn reduces the running cost and improves efficiency.

A PUMP FOR ALL SEASONS Certikin are Calorex’s exclusive trade supplier and say that Calorex heat pump technology offers an extremely efficient method of pool water heating which fortunately does not rely upon sunshine, just air! 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.


LIGHTHOUSE BRINGS ZODIAC INTO THE UK MARKET Lighthouse Pools has launched one of Europe’s leading ranges of heat pumps from Zodiac into the UK market for 2011.


Zodiac brings a high level of technical expertise with the units, which suit any pool-size and location. The company can boast over 30 years experience as a dedicated manufacturer, with heat pump sales exceeding 100,000 worldwide.


With the support of Zodiac Pool Care Europe, Lighthouse Pools offer quiet, efficient and cost effective heat pumps backed up by the assurance of a UK service centres, stock on hand for immediate dispatch and a quality after sales support.


The benefits of introducing the Power, Power First and Eden Pac ranges include efficiency, low noise level and integrated digital controls. There is a lifetime warranty with the titanium heat exchangers. The Zodiac range is extensive and suits pools up to 200m3. spn
