The short answer

A heat-pump proposal should explain your home’s needs, the changes to the heating system and how performance was estimated.

Describe the existing home

Collect heating bills, room sizes and information on insulation and ventilation. Explain which rooms are uncomfortable and how you use hot water. Tell the designer about planned renovation so the system can be considered alongside the building’s future needs.

Compare the complete scope

Check whether the proposal covers radiators or other emitters, a hot-water cylinder, electrical work, controls and removal of old equipment. Ask about outdoor-unit location, sound and maintenance access. Compare the same comfort requirements and electricity-price assumptions across offers.

Connect advice with the project

France Rénov’ can help orient your renovation plan and explain support routes. Ask which professional qualifications and technical conditions apply before relying on aid. Keep the technical choice separate from an advertisement promising a particular grant.

Define the services you want to replace

An air-to-air heat pump and an air-to-water system do not provide the same installation. Specify whether the project covers space heating, hot water, cooling or a combination. Describe existing radiators, underfloor heating and cylinder space. A quote that leaves hot water on the old system should show that clearly, including the remaining running and maintenance costs, so the complete household arrangement can be compared.

Ask for a room-by-room explanation

Request the heat-loss assumptions, proposed water temperatures where relevant and any emitter changes for each room. Include insulation improvements already planned. Ask how the system responds on cold days and what supplementary heating, if any, is expected to do. The designer should connect these choices with comfort and estimated electricity use rather than presenting equipment capacity as the only meaningful specification.

Plan the first month of operation

Agree who demonstrates the controls and how you obtain help after the installers leave. Record starting meter readings and the normal settings explained at handover. Learn how to change a comfort schedule without altering technical configuration. Arrange a review of any persistent cold rooms, unusual noise or unexpected consumption, using a record of the conditions rather than repeated untracked changes to the controls.

Your planning checklist

  • Heating, hot water and other requested services identified.
  • Room heat loss and emitter changes explained.
  • Outdoor location, access and electrical scope agreed.
  • Handover settings, support contact and early review arranged.

Common questions

Can a quote be based only on the old boiler’s power?

That is not enough to explain the new design. Ask for the building’s heat requirement and the proposed system’s operating conditions. An existing boiler rating does not by itself describe the heat each room needs.

Should I choose the equipment mainly around the aid offered?

Start with a design that fits the home, then check the relevant support conditions with France Rénov’. A contribution changes the budget; it does not establish that a particular installation will meet your comfort needs.

A practical next step

Request a written design explanation, a detailed scope and a handover plan that includes settings, maintenance and who to call for help.
