Navigating the heat pump options

As there is no ‘one size fits all’ approach to heating, it’s important to be aware of the wide range of technologies. Richard Paine, Product Manager at Daikin UK, discusses the diverse range of air source heat pumps available and how to recommend the most suitable system.

With multiple types of properties requiring heating – from small business premises to all varieties of houses – there is no one solution for cost effective and energy efficient heating. To ensure an appropriate system for every property and to meet the client’s needs, installers should have a wide range of heating technologies available to them. This means they can recommend the best solution for each individual client, based on the property’s energy sources and requirements.

Additionally, the customer’s preference and current knowledge of heating systems is a significant factor in recommending the correct product. Some clients may only be comfortable with a like-for-like replacement, whereas others may be totally switched on to the benefits of renewables. So, if an installer is well informed they can help the client make a decision on the best solution for them.

Our Altherma range of heat pumps – which includes a low temperature monobloc system, a low and high split temperature split, plus a hybrid solution – has been designed to enable installers to meet the specific requirements of each property.

Installed entirely outdoors and only requiring a domestic hot water cylinder, the Altherma LT Monobloc is best suited to applications where available indoor space is at a minimum. The all-in-one unit saves valuable space within the property, and is quick and easy to install. Furthermore, the unit installation doesn’t require refrigerant handling and therefore F-Gas certification, as only water and power connections are needed.

Designed with larger properties in mind, the Altherma Low Temperature (LT) Split delivers approximately 5kWh of usable heat for every kWh of electricity consumed. With the highest seasonal and part load efficiencies, the LT system is ideal for harsher climates with severe winter conditions. This is due to frost protection, which guarantees performance in temperatures as low as -25°C. A split unit, the installation does require F-Gas qualifications, as refrigerant pipework is needed to connect the outdoor unit and indoor hydrobox.

Retrofit solution
For older properties and retrofit projects, our High Temperature (HT) Split system could be the ideal solution. Delivering flow temperatures of up to 80°C, the system provides cost effective heating. Connecting to existing pipework and radiators, the new system is simple to install and the hot water tank can be placed on top of the indoor unit to save space.

For homeowners who would prefer the familiarity of a gas boiler, but want to lower their heating costs, our Altherma Hybrid is the environmentally friendly solution. A renewable heating system combined with a traditional gas-condensing boiler, it offers the ‘best of both worlds’.

Funding advice
Although a challenge, keeping up to date with the latest legislation and funding opportunities will also help you advise your client on the most suitable product. The government-funded Renewable Heat Incentive (RHI), for example, offers financial support to properties that choose a renewable, green technology for their heating solution based upon the amount of heat that the system produces. Therefore, a property owner looking to reduce heating costs would benefit from a low cost, renewable heating solution that earns an RHI tariff. 

Heat pumps can also be combined with other renewable technologies, including solar thermal, for further decreases in energy use.

The extensive factors influencing a single property’s heating requirements means there is no one size fits all solution. However, by having access to an extensive product portfolio and expert industry knowledge, installers can provide a sound product recommendation to each and every customer.
