Mitsubishi Heat Pump

The only type of heat pump we install is Mitsubishi. The Mitsubishi Ecodan Air Source Heat Pump is arguably the best Air Source heat pump available. Mitsubishi are based in the UK with manufacturing plants in Scotland. They have a dedicated team for technical queries and parts. Unlike their competitors who use distributors in the UK.

The Mitsubishi Ecodan Air Source Heat Pump is arguably the best Air Source heat pump available.

 

Mitsubishi Electric has launched some of the quietest air source heat pumps ever available in the UK to offer complete flexibility on where units can be installed whilst meeting Permitted Development.

The Ultra Quiet Ecodan air source heat pumps are available in 8.5kW and 11.2kW sizes with sound levels that are three times quieter than previous models, virtually eliminating planning restrictions.

Designed specifically for residential applications, these models offer superb, market-leading energy efficiency and sound levels and enable almost any home to benefit from high performance, renewable heating. 

“The government has already recognised how important air source heat pumps will be for the future of low carbon heating in the UK and is forecasting one million sales a year by 2030,” says Max Halliwell, Product Manager for the company’s renewable heating systems.

“One of the key areas that will affect adoption of these energy-saving systems is noise which is why permitted development exists and these new units are designed specifically to overcome any issues with noise.”

In the residential environment, sound is important because low sound increases the flexibility of where a heat pump can be positioned. To ensure neighbours aren’t disturbed, Permitted Development requires sound levels to meet certain limitations, with the sound pressure level not exceeding 42 decibels, dB(A) when measured at a point one metre away from the neighbour’s nearest door or window.

The 8.5kW Ultra Quiet Ecodan has a sound power level of only 58 dB(A) which is an 8 dB(A) drop over the model it replaces.  It also has a sound pressure level of just 45 dB(A) at one metre.

Sound power can be thought of as the cause of a noise or the total sound energy emitted by a source in all directions, whereas sound pressure is the effect or the sound we hear and this is determined by the environment and by the distance from the source of sound. We think of this as the intensity or loudness of a sound. An ambulance registers 120 dB(A) whereas a vacuum cleaner registers around 73 dB(A) and typical room conversation comes in at around 60 dB(A). 

“With a sound pressure level of just 45 dB(A), the new Ecodan is whisper-quiet, with levels just above that of a library, meaning it will pass the Permitted Development requirements easily and can be installed almost anywhere to suit the homeowner,” explains Halliwell.

“This is a result of a decade of manufacturing Ecodan in Scotland and we have used this knowledge and experience to refine Ecodan and design it specifically for UK residential use.”
