 | Mitsubishi Electric says the low sound levels of its new air source heat pumps means there is even more flexibility in where they can be installed. The Ultra Quiet Ecodan is available in 8.5kW and 11.2kW sizes with sound levels that are three times quieter than previous models, virtually eliminating planning restrictions. Designed for residential applications, Mitsubishi claims market-leading energy efficiency and sound levels that enable almost any home to benefit from high performance, renewable heating. |
Max Halliwell, Product Manager for renewable heating systems, said: “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.
“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.”
To ensure neighbours are not 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.
Halliwell added: “Our market leading Ecodan heat pumps have always been amongst the quietest on the market and are designed to provide any home with reliable, trouble-free renewable heating and hot water. New Ultra Quiet Ecodan takes this to the next level with low sound and high performance which mean homeowners can now choose the most convenient location for their heat pump, giving complete flexibility on placement and still meeting Permitted Development requirements.”
Innovations
The 8.5kW Ultra Quiet Ecodan has a sound power level of 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 relates to 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 is determined by the environment and by the distance from the source of 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).
Halliwell added: “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.
“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.”
Innovations in fan and compressor design have enabled the units to achieve low levels of sound whilst increasing performance and efficiency. Both models are A++ ErP rated and available with coastal protection for areas where they can be exposed to saline.
