The New Heat Pump Owner's Operating Manual: How to Run Your Air-to-Water Heat Pump Comfortably and Efficiently, Understand the Controls and Know When Something Isn't Right

Your heat pump has been installed. The installer has left. Now what?

If your radiators feel cooler than they did with a boiler, the outdoor unit seems to run for hours, hot-water heating interrupts the radiators or your electricity use suddenly looks alarming, it is easy to start changing settings without really knowing what they do.

The New Heat Pump Owner's Operating Manual is a practical UK guide for householders with domestic air-to-water heat pumps.

Instead of giving you somebody else's "perfect settings", it shows you how to understand what your own system is doing, establish a useful baseline and make sensible owner-level adjustments without drifting into installer-only work.

You'll learn how to:

• understand flow temperature, heating controls and weather compensation
• use schedules and setbacks without trying to operate a heat pump like a boiler
• understand domestic hot water, defrost, frost and long run times
• investigate a house that is too cold, too warm or unevenly heated
• make sense of unexpectedly high electricity use
• record warnings and fault codes before taking action
• recognise when troubleshooting should stop and professional help should begin

At the heart of the book is a simple five-stage method:

BASELINE → OBSERVE → ADJUST → CHECK → ESCALATE

This is not an installation or repair manual. It is a practical owner's guide to running your heat pump comfortably, efficiently and with a much clearer understanding of what is normal and what deserves attention.
