Air Source Heat Pump installation in Cornwall

FAQs – Heat Pumps

How often does my heat pump need to get serviced?
It is a requirement to have you heat pump serviced every 12 months to maintain its warranty. Much like a traditional gas or oil boiler a ground source or air source heat pump needs to be serviced annually to keep its manufacturer warranty as well as maintaining its efficiency and safety levels.

Do you cover all of Cornwall?
Yes, we have engineers covering all of the Dutchy.

What’s included in a heat pump service?
Knowing what’s included in the service will demystify the process and make you feel more confident that your boiler has been well taken care of.
The service will vary a little between different providers, but here’s a general idea of what to expect.

The main components applicable to a standard closed loop heat pump system that will need checking are:

  • The electronics and control equipment
  • The water pump – the only moving item in the system
  • The compressor – if this unit fails it will have to be replaced as a whole as it is a sealed unit
  • Pipes and connectors (above ground)
  • Glycol anti-freeze levels – check for correct chemical mixture
  • Heating checks – check radiators and bleed system / underfloor heating / check fluid.
  • Clean and or swap out filters
  • Clean coils and fans (if necessary)
  • Ensure proper air flow is not impeded by debris (leaves, dust etc.)
  • Clean the supply and return registers inside the property
  • Power off the unit and check / clean fan blades.
  • Before the winter (or summer if used for cooling) it is recommended to have the unit serviced by a professional who will conduct a more advanced audit of the components and identify issues that could degrade the heat pump’s performance, which a user would not spot or be able to diagnose. These checks will comprise of the following:
  • Check for system leaks
  • Check reverse heating / cooling controls and verify they are operating as required
  • Lubricate moving belts, motors and check for damage / wear and tear
  • Check and test thermostat under normal operating conditions.
  • As with all devices containing or designed to contain F-Gas refrigerants, an ‘F’ Gas certified engineer will be required to work on these components.
  • Check ducts for leakage and repair if necessary
  • Inspect filters, ducts, blower and indoor coil for dirt and other obstructions
  • Measure airflow is correct
  • Check refrigerant levels and pressure
  • Check all electrical connections, check voltages, amperage, check all PCBs

We started projects with estimates which S Annear completely adhered to in 2015 and 2019. Subsequently any emergency callouts to any properties have always been promptly answered. A friendly, helpful team – you couldn’t ask for more,


Simon Annear Review

Rated 5 out of 5
June 30, 2022

Ours was a retrofit of a 12kw Vaillant Air-source recovery pump system in replacement of an oil-fired boiler which served an existing wet system in an enlarged 3-bedroom traditional cottage.
We have to say that from the outset the advice and guidance received from Simon Annear staff was excellent, and was delivered over several visits, always at our request.
The installation itself took place in late 2021 just as The Omicron phase of the pandemic became evident, and despite consequent staffing and supply-chain challenges, Simon Annear staff completed the main elements of dismantling the old and installation of the new systems within 3 days. Remarkably to us, all of this work was carried out in a very clean and orderly manner, and without significant disturbance to us.
A couple of ‘fine-tuning’ visits from engineers over following days saw the system running as promised, and we have enjoyed living with the new heating system over winter into spring and can further confirm that our system appears to run at broadly comparable cost to the combined mixed electric/oil-fired example previously employed.
Without reserve we would recommend Simon Annear to anyone considering a similar conversion.

The chap who attended the property was excellent. Unfortunately there was nothing he could do as the boiler and meter was a commercial one as it’s a big house. He directed me to someone who could help, after consulting with his boss. I would certainly use your company again. He was very polite and professional.

Simon Annear submitted the best technical solution for changing our boiler. We were not present for the installation but everything worked ok when we used it and subsequent service visits have been most satisfactory. We would definitely use them again.

Simon Annear have always been prompt and helpful. They installed the plumbing and heating on our new build and have returned periodically for services etc. The heating system was Air Source with underfloor heating and Solar Panels.
The installation was excellent as has been subsequently serviced. Highly recommended.

Simon and his team (particularly Dan and Kieran, both outstanding) did an excellent job of installing an air source heat pump with underfloor heating and hot water. Furthermore, they also fitted out two bathrooms – all to a very high standard. Dan and Simon were meticulous in the planning of the installation and did their utmost to fit in the work around our barn conversion. A professional and highly recommended company.

Radiator repair

Radiator fell off wall in lounge and fractured inlet pipe. This was all repaired and replaced by young man called Tom who was respectful of our home and his workmanship was second to none. He is a credit to Simon Annear Plumbing.

As usual, service was carried out efficiently. Cheerful technician & worked very cleanly. Would have given 5 stars but arrived 2 hrs late. Not his fault but office should have advised us. It was no problem to us but may have been if we’d had other appointments. However, well done as usual.

Lovely young man came to look at my heated towel rail that didn’t come on when I turned the central heating on last month. Turned out it was human error on my part, but it was checked and then explained which tap did what. Very helpful, knowledgeable and friendly young man.
