Vaillant adds to successful air to water heat pump range aroTHERM

Heating technology manufacturer Vaillant has unveiled two new additions to its range of aroTHERM domestic air to water heat pumps. The new 5kW and 15kW outputs complement the existing 8kw and 11kw models, giving installers and homeowners increased choice.

In expanding the aroTHERM range, Vaillant is taking a significant step towards reducing the cost and complexity of domestic renewable heat sources—previously considered a barrier to uptake . Vaillant’s focus on developing flexible and affordable systems will help to make heat pumps a viable option for anyone looking to introduce renewable energy into their homes and to promote a shift away from traditional, expensive heating measures.

As with the existing models, the new additions to the range can be used in both new and existing buildings and can work as a standalone technology or integrated into a hybrid system using an oil or gas boiler and/or solar thermal technology

The new aroTHERM outputs also introduce two new sizes to the range—with the 5kW the smallest (H834mm x D408mm x W970mm) and 15kW the largest (H1375mm x D463 x W1103mm)—affording more flexibility for different applications. The refrigerant circuit within the heat pumps is hermetically-sealed, therefore installers do not require a certificate of proficiency for the handling of coolants or cost-intensive special tools.

System kits and accessories are available, including a back-up heater, a wall-hung 40 litre buffer tank, and a heat exchange module, making aroTHERM straightforward to specify, order, and install. Both standalone and hybrid systems include the weather compensated control unit VRC470 as standard, which helps to get the highest possible efficiency levels out of your system.

The products’ timely release also follows the activation of the domestic RHI scheme in April 2014. Mark Derbyshire, commercial director at Vaillant, comments: “With over 1,000 installations accredited in the first few weeks of the scheme’s launch, it’s clear that renewable technology is rising up the agenda for homeowners.

“The new 5kW and 15kW models expand upon the existing aroTHERM range to offer our customers an air to water heat pump which is attractively priced but still meets all of Vaillant’s high quality standards. As with the rest of our products, all of the design, development, and manufacturing work is carried out by Vaillant itself.”

The aroTHERM air to water heat pump range also joins the ranks of other Vaillant products—including the geoTHERM ground source heat pump and the ecoTEC range of boilers —to have been awarded Quiet Mark accreditation from the UK’s Noise Abatement Society. The accolade serves to recognise excellence in products that succeed in combining quality technology with reduced noise levels.

Mark continues: “The addition of two new outputs to our aroTHERM range further underlines Vaillant’s commitment to the renewable sector and to providing clear, flexible solutions for homeowners.

“We have also recently launched an online Renewables Calculator that enables users to quickly and easily calculate their potential savings should they switch to renewable technology, while our Vaillant Village Green road show is also touring various locations across the country partnering with renewables installers, promoting renewable technology and the various funding streams now available to homeowners.”

Each of the aroTHERM models is compatible with a the entire range of Vaillant ecoTEC boilers, but also with a wide variety of third party gas, LPG, and oil boilers, allowing the heat pump to be easily retrofitted with existing heating systems to provide efficiency benefits.

Mark adds: “aroTHERM works perfectly and seamlessly in conjunction with an existing heat generator. In return for comparatively low investment costs, owners can massively increase the amount of renewable energy that they use for heating – they also ease the burden on the environment at the same time.”

The control unit further ensures that the system provides significant carbon and running cost savings by selecting the most cost-effective fuel to use based on energy tariffs. The intelligent heating control selects the lowest cost energy source, and a unique triVAl control system means three possible energy tariffs can be entered. In warm periods, the new heat pump provides additional comfort in a cost-effective and environmentally friendly way with its active cooling function.

The 5kW and 15kW aroTHERM models will be available from 1 August 2014.
