Permitted2026/0155Submitted 5 months agoHeat pump

Lavenham Road Wandsworth SW18 5EP

We intend to install a 12-kilowatt air source heat pump, specifically a Mitsubishi Ecodan R290 (Model: PUZ-WZ85/100/120V/YAA), to provide both heating and hot water for the facility. The unit will be located in the alleyway behind the hall, positioned between the building and the fence bordering the vicarage garden. This placement ensures that the unit will not be visible to any surrounding houses. Additionally, the heat pump will be situated 14 meters away from the nearest dwelling, which is the vicarage. Please note that there is currently an existing AC unit collector located at the opposite end of this same alleyway. Sound levels We have selected this particular unit as the Ecodan R290 has received QuietMark approval: https://www.quietmark.com/products/mitsubishi-ecodan-r290-air-source-heat-pump-12kw. The unit hits 55 on sound power level Here is an explanation of how QuietMark assesses appliances for their standard: https://www.quietmark.com/how-quiet-mark-certifies-products. We estimate that the decibel level at the nearest house will be 21.1. Calculations are in an attachment
