How much heat does each room need?
We check the property room by room, including insulation and glazing, so the system is sized for the heat your rooms lose.
Air source heat pumps
A heat pump that works for your property.
Replacing your heating takes more than choosing an outdoor unit. FLO starts with a free survey, checks the whole heating system, then explains what installation would involve and cost.
The survey helps establish what is possible. It does not commit you to an installation.
Real FLO heat-pump installationBefore choosing a system
Will a heat pump work well in your property?
That depends on the building and the heating already inside it. A free FLO survey checks the things that shape comfort, equipment size and installation cost.
Will your radiators deliver it?
We look at radiators or underfloor heating, pipework and the temperatures they need. Any changes should be clear before you commit.
Where will everything go?
The outdoor unit needs a practical position. We also check hot-water storage, electrical supply, drainage and routes between them.
What you get from the survey: a clearer view of whether a heat pump is worth designing for your property, what else may need changing and what needs a closer look.
From first question to working heat
How does a FLO installation work?
Each stage answers a different question, so you can see the scope before deciding to go ahead.
- 1
Tell us about your property
Start with a few details about your current heating and what you want to improve. You do not need to know which heat pump you need.
- 2
Have a free property survey
FLO checks heat demand, existing heating, hot water and the possible equipment locations. This is where a generic idea becomes a property-specific plan.
- 3
Review the design and written quote
You should see the proposed equipment, any radiator or electrical work, the full installation scope, price and what is not included.
- 4
Plan and carry out the work
Before work starts, agree the sequence, access and likely disruption. FLO then installs the heating equipment and any agreed supporting work.
- 5
Commission and learn the controls
The finished system is checked and set up. You should know how to use it, what documents you receive and who to contact afterwards.
Before you decide
What will your assessment and quote cover?
The proposal should show the complete job, not just the price of the heat pump. FLO uses the property survey to set out what is recommended and what it will take to install it.
- The heating designHeat loss, proposed heat pump, operating temperatures and any radiator or underfloor-heating changes.
- The whole installationOutdoor position, hot-water cylinder, pipework, electrical work, controls and any agreed enabling work.
- The decision detailsWritten price, what is included or excluded, the expected programme and any checks still outstanding.
- After installationCommissioning, handover, controls guidance and the support route.
Practical questions
What else should you know?
How long does installation take?
The programme depends on emitters, cylinder, electrical work, access and whether the building remains occupied. The written proposal should state the expected sequence and disruption.
Will the heat pump work during cold weather?
It should be selected against the building's design conditions. Ask for output and heat-loss assumptions at the relevant outdoor temperature, not only a nominal brochure rating.
Can the old boiler remain as backup?
Sometimes a hybrid or temporary arrangement is justified, but it changes controls, carbon and operating logic. The design should state when each heat source runs.
Will I need new radiators or a hot-water cylinder?
Possibly. The survey checks whether your current radiators can heat the rooms at the proposed water temperature and whether your hot-water setup is suitable. Any changes should be listed in the quote.
