SPN APR 2010 HeatPumps

ABOVE: Thermalec are beginning to enjoy the benefits of the heat pump market after launching at SPATEX last year with a range of pumps from 4.5kW to 60kW – ideally positioned to reduce energy costs and offer low noise levels

get a product that is perfectly suited to our climate. As with most Canadian pool products where build quality and component parts are quality assured, Waterco’s Electro Heat Plus range is no exception. The new Sub Zero models are a great addition to this range.” All Waterco heat pumps are manufactured at Waterco’s Canadian manufacturing operation located in Quebec, Canada. Climexel Heat Pumps manufactured in Europe by Procopi are another top range made to the highest standards with a loyal pool ownership following. The whole range are reverse cycle defrost models, and so work down to -15°C air temperature.

They have all been tested to the European “Eurovent” Standard at 15°C air temperature and all the output figures use this much more

conservative air temperature rather than the extremely rare (in the UK) 250°C that many of our competitors use to boost their performance figures.

Climexel heat pumps achieve COPs of around five at 15°C giving an output of 5kW for every 1kW input power. Output figures of 7kW to 120kW means there is a unit for any application, even large commercial pools. With noise levels at 39-44db across the range these units are extremely quiet and environmentally friendly. 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 remain the key to the market continual growth. Everything else seems to be working in its favour. spn

Certikin’s Julie Pringle, argues that we should all become acquainted with renewable heat technology before the likelihood of enforced legislation.

Hot water production for the majority of domestic and commercial applications has traditionally involved burning fossil fuels, such as gas and oil. The detrimental effects

of the CO2 implications on our environment has led the search to find climate-friendly alternatives. In the domestic house building market, current government

regulations and Building Controls mean renewable sources of energy need to be used to enable the building to satisfy both SAP (Standard Assessment Procedure) requirements and codes for sustainable homes. Soon these rules will apply to the swimming pool building as well. By 2016 the Government will have ruled that no new gas supplies will be allowed to new build sites, meaning that they will be stuck with oil, LPG or electricity unless alternative methods are used. There is also pressure from the customer who, initially motivated to reduce the running costs of their pools is also keen to find ways of caring for the environment and reduce their own carbon footprint. Calorex has a range of Ground Source Heat Pumps (GSHP) and Air Source Heat Pumps (ASHP) for this purpose.

The 29 range and the new ProPac range, introduced last year, are examples of the outdoor heat pumps utilising this technology. Calorex’s air handling / indoor pool environmental control units, such as the Delta and HRD, use heat pump technology for the dehumidification process and the recovered heat from this process is put back into the pool water and the pool hall air. A source of low pressure hot water (LPHW) is required to top up the water and air heating via heat exchangers integral to the air handling unit – this is where fossil fuel boilers (usually gas) are used. However, Calorex have now adapted the technology whereby another heat pump can be incorporated to produce LPHW.

ASHP units are generally installed outside the pool hall and extract heat from the ambient air providing LPHW to the air handling unit. In contrast, GSHP units are generally installed in the pool plant room and, via pipes buried in the ground, they extract solar thermal

energy from the ground. This is energy from the sun so a renewable source of energy.

ASHP’s and GSHP’s are much more efficient than fossil fuel boilers (GSHP’s can be up to 400% efficient!), so running costs are greatly reduced. As there are no fossil fuels on site, there is no risk of gas explosions, oil leaks or carbon monoxide poisoning, making it a much safer option all round. So it is a simple integration – it’s only a hot water supply.

Heat pump technology is not new – it’s old and it’s proven and there is a large amount of financial help available:

• Enhanced capital allowance (ECA) – allows units to benefit from 100% write off against taxable profits in the first year. The Calorex Delta 14 and 16 are the only swimming pool environmental control units eligible for ECA. See

• Carbon Trust – Private sector organisations who have been trading for at least 12 months can apply for interest free loans. The project must show cost effective carbon saving – Certikin can produce approximate heat pump running costs for the project as well as those for competing fuels. See

• Microgeneration Certification Scheme (MCS) – MCS is an independent scheme that certifies products and installers in accordance with consistent standards providing reassurance to the customer. Calorex ASHP models AW4500 and AW4502, AW9000 and AW9002, AW12000 and AW12002 and GSHP models WW3500, WW5000 are all MCS accredited. MCS is a method of making a contribution to cutting the UK’s dependency on fossil fuels and carbon dioxide emissions. See

Renewable Heat Incentive (RHI) – The Department of Energy and Climate Change (DECC) announced on 1 Feb 2010 plans for a scheme to give incentives for renewable heat generation. This will come into effect in April 2011 and guarantees annual payments for those who install technologies such as GSHP or ASHP. Payments will be assessed on an individual basis depending on the size and heat loading of the property. As long as the GSHP or ASHP are providing an amount of heating or domestic hot water for another part of the property as well as the pool, then the customer will be eligible for RHI payment. The units installed and the installer must be MCS accredited to qualify for RHI payments. The RHI could help thousands of customers who are off the gas network to lower their fuel bills and hence reduce running costs.
