The quick-start guide

Everything you need to know about your heat pump and how it works in your home.

5 top tips for getting to know your heat pump

1. It'll adjust to the weather automatically

To help you save energy, we set your heat pump to monitor how hot or cold it is outside, and adjust the temperature accordingly.

2. Heat pumps take longer to warm up

Your heat pump uses cooler water to heat your home, so it can take longer to warm up. You won’t feel an immediate difference like you might be used to with a boiler. It’s best to set your heating to come on before you get home or wake up. The preheating time will depend on your home, so you may need a few trial runs to find the perfect schedule.

3. Hot water always takes priority

When it’s time to heat your hot water tank, your heating will switch itself off. When the tank’s ready, the heating will turn itself back on. You don’t need to do anything and you shouldn’t notice too much of a difference in your home’s temperature.

4. It’s better to turn the target temperature down than to turn the pump off

Your pump is much more efficient when it’s running consistently. We recommend only turning the temperature down but a couple of degrees rather than turning it off completely, unless you're going away for a few days. This means it will use less energy than it needs to heat a cold house, as it doesn't have to work as hard to keep your home cosy.

5. Keeping the area around your pump clean and clear helps it work well

The box needs room to breathe, so don’t pile the garden furniture or pots nearby. It also helps to clean off any leaves or dirt, and brush away snow. If you fancy a spring clean, you can give it a wipe down with a damp cloth, but steer clear of harsh chemicals, and avoid touching the fins at the back to protect your hands and the heat pump.

How to save energy and money

  • Keeping a steady temperature will save you money
    Avoid turning up the comfort target temperature by more than a couple of degrees to keep your heating running efficiently. Stick to a target temperature that suits your comfort and budget, and your heat pump will adjust to the weather outside. Check out this guide for tips on the most affordable ways to run your heat pump.

  • Set a schedule
    Turning your heat pump on and off will use more energy than setting a schedule in advance - your heating is designed to keep ticking away efficiently when it’s scheduled to be off, without cooling completely.

    If you’re on a tariff that has peak and off-peak times, try setting your heating and hot water for when you’re paying the lowest rates to save more money. Find recommended schedules here.


  • Go easy on the heating boost
    It’s a handy shortcut when you need to reheat the tank or warm your home quickly. But it’s not the most efficient way to use your system. So it's best to save it for when it’s really needed.

  • Choose a smart tariff
    With a smart tariff like Cosy Octopus, you can heat your water cylinder at the cheapest and greenest times, saving you money with smart energy usage.
