Heading Air source heat pump and ASHP + cylinder servicing plans
We offer in-warranty servicing plans for your heat pump and your ASHP
cylinder, with visits carried out by trained engineers to check key
components and note any visible issues. There are separate plans for
either the heat pump and the ASHP + cylinder, and each plan can be
paid in full or spread over monthly payments. This gives you the
flexibility while making sure both systems are checked according to
guidance. These inspections are carried out at recommended intervals,
helping ensure your heat pump and ASHP cylinder stay in good working
order.
