Project details
Choose the nearest location (Northampton uses Birmingham). For properties well above sea level, lower the temperature by 0.6 °C for every 100 m above the location.
Technical assumptions
U-values are typical figures for the age, wall, glazing and loft choices, not verified construction details. Room temperatures follow the room type. Ventilation is set per room from the property age, with an allowance for kitchens and bathrooms; rooms with no outside wall or roof get none. You can override the temperature and air changes in any room.
Rooms in your project
Room measurements
Start from existing plans
Important: A photograph is not automatically to scale. Calibrate against a dimension printed on the plan, then verify every measured room before using it. For a PDF plan, take a screenshot of the page and upload it as an image.
Visual floorplan
Choose a floor, then copy its lower-floor layout as a starting point. Check the room names, windows, doors and insulation on each floor.
Exact room measurements — Selected room
Draw or drag the room roughly, then type the exact measurements. No grid rounding. Tap a measurement inside a room to edit it here.
Edit the L-shaped recess here, or pull a new wing outwards from a rectangle below. Drag either white + grip on the L to adjust its inner walls.
Tap each of the six visible wall segments in Outside walls mode to mark them correctly.Start with a rectangular room, choose which side to extend, then drag the new L-shaped walls or type precise measurements. An extension adds floor area, rather than cutting it away.
For an existing drawing, choose “Re-detect ALL outside walls”. If a short red section is still internal, choose Outside walls and tap that exact red segment to turn it grey.
Drag rooms into place and resize walls. Choose “Move whole layout” to reposition every room on the selected floor without disturbing their arrangement. Edges snap together and overlaps are blocked. Use Undo erase if needed. External walls are detected from the completed floorplan. Where rooms touch only along part of a wall, that wall is split into external and internal sections. Very small drawing gaps (under 8 cm) are treated as touching if the rooms face each other. Choose Outside walls and tap any incorrectly coloured wall SECTION to correct just that section. Re-detect outside walls clears overrides; check real gaps and unheated spaces.

Will the heat pump also provide hot water?
Indicative starting point: 45 litres per person plus 40 litres, rounded up to a common cylinder size. High demand adds 50 litres. Kingsley will confirm usage, coil compatibility and reheat time.
Which manufacturers would you consider?
Sizes are preliminary capacity classes from published ranges, not a confirmed model selection. Where a load sits close to a size, both sizes are shown. Kingsley will check cold-weather output and emitters before quoting.
