Best water heating and renewable options from Ariston_1

The combination of renewables and domestic hot water (DHW) can be a winning one, especially when it’s been specified and installed correctly. However, when it comes to specifying the right product for the job, installers are faced with a wide range of options. So as renewable technology continues to evolve, what are the best choices for the provision for DHW?

With cost savings in mind, there are several options to consider. The first is solar thermal, which has been a popular choice for integration into a building’s heating system to provide DHW. And certainly the final tally at the end of the Renewable Heat Premium Payment (RHPP) would back this up, with 31 per cent of grants supporting solar thermal installations.

Taking another glance at the stats for the RHPP will show heat pumps account for over half of those issued, with air source heat pumps (ASHP) proving to be the most popular type. The main reasons for their popularity are simple: they can be easily integrated into existing properties, are versatile for different property types, and once installed, they more often than not function completely automatically. Plus, when it comes to running costs, ASHPs have excellent coefficients of performance (CoP).

Still, if there was a downside to mention about the current crop of ASHPs, it would have to be their large size. That’s why some manufacturers are now looking to offer alternatives to the high power ASHP’s on the market, with products that focus solely on renewable hot water production. These new, ‘adapted technologies’ allow more properties – especially those in off gas areas – to incorporate renewable energy and use it effectively.

One newly developed product that fits the bill is Ariston’s own NUOS integrated ASHP with an unvented cylinder. This harnesses all the benefits of quick and efficient hot water delivery alongside the benefit of high CoPs - making them an excellent alternative to traditional electric storage water heaters. Plus, for many properties where space is an issue, these products are sited within a property and help contribute to considerable reductions in household utility costs.

By keeping up to date with these latest innovations, installers will be able to offer homeowners alternatives that might not have been considered, and demonstrate that the combination of renewables and DHW is still as good as it’s ever been.
