Plan the site before choosing a heat pump water heater

Ask your installer to assess air supply or ducting, condensate drainage, access, sound and the unvented discharge route. Heat pump performance depends on air temperature and operating conditions, so a headline energy rating is only part of the decision. Confirm the current connected-service support and warranty arrangements for this product code before purchase.
