I’ve no issues with an annual service of an ashp in particular to keep the warranty up. But I’ve noticed on our new hot water cylinder that it states on a big sticker that it must be serviced each year in order to keep the 10year warranty.

I have never once had a water cylinder serviced. It’s obviously a good game, not least to void a guarantee.

2kW + Growatt & 4kW +Sunnyboy PV on south-facing roof 9.5kWh Givenergy battery with AC3. MVHR. Vaillant 7kW ASHP (new & still learning it)

It would be interesting to find out what is actually carried out when a DHW cylinder is serviced?

You should have been left the service manual and commissioning certificate with the new cylinder.

The annual service for unvented cylinder includes testing safety valves, recharging pressure vessels, cleaning the pressure reduction valve strainer, checking electrical connections and providing a service certificate. All pretty basic stuff but you need to be G3 certified to complete the work.
