Every project below is a real BHL installation across Cheshire and South Manchester. Each one sets out the brief we were given, the technical approach we took and what the client ended up with. Where a job taught us something worth passing on, we have said so. ## How we approach every project The pattern rarely changes. A free survey establishes what the property is actually made of, a room by room heat loss calculation sets the design, and only then does anyone talk about products. Underfloor heating quotations come back within 24 hours. Heat pump quotations take 3 to 7 days, because the MCS calculation is done properly rather than estimated. On site, installations typically run 1 to 5 working days with 2 to 3 days being the average. We work in occupied homes as standard, Monday to Friday, 8am to 5pm. Our workmanship is covered for 2 years, and we hold MCS accreditation, NAPIT registration, RECC membership and Gas Safe registration. Wilmslow, SK9 ## Retrofit floor milling across a 1930s ground floor ![Retrofit floor milling cutting underfloor heating channels into a concrete ground floor in Wilmslow](/assets/floor-milling-1-DOR5FEa7.jpeg) **The brief.** A four bedroom 1930s property with a solid concrete ground floor, tiled hallway and a kitchen extension the owners had no intention of disturbing. They wanted underfloor heating throughout the ground floor without lifting a single finished surface they cared about. **Our approach.** A room by room heat loss calculation set the pipe spacing and the design flow temperature at 38 degrees. We milled channels directly into the existing slab using dust extracted equipment, laid 16mm pipe into the channels, reinstated and pressure tested before any floor finishes went back down. Zoning was split across five circuits so the hallway, kitchen, dining room, lounge and utility could each hold their own setpoint. **The result.** Floor levels rose by a matter of millimetres, so no doors were trimmed and no skirtings were replaced. The system runs at a low enough flow temperature to be paired with an air source heat pump later, which was the owners' stated five year plan. 3 working days on site Bramhall, SK7 ## Low profile overlay system over a suspended timber floor ![15mm low profile overlay underfloor heating panels laid over an existing floor in Bramhall](/assets/overlay-panel-2-CREXGrQv.jpeg) **The brief.** A first floor renovation in an occupied family home where milling was not an option because the substrate was suspended timber rather than concrete. The brief was warmth underfoot in the bathroom and two bedrooms with minimal build up. **Our approach.** We specified a 15mm low profile overlay panel system laid straight over the existing deck. Because the panels add so little height, the existing door set stayed in place. Pipe was routed to a compact manifold sited in the airing cupboard, keeping pipe runs short and pressure loss low. **The result.** Total floor build up of 15mm plus finish. The bathroom now reaches temperature well before the rest of the floor because of tighter pipe spacing under the tiled area, which was a specific request from the client. 2 working days on site Macclesfield, SK10 ## Zoned Heatmiser control replacing a single stat system ![Zoned Heatmiser underfloor heating manifold with actuators wired for multi-room control in Macclesfield](/assets/manifold-heatmiser-2-zfTuuLlC.jpeg) **The brief.** An existing underfloor heating system installed by others, running the entire ground floor from one thermostat in the hallway. The living areas were overheating while the far end of the property never warmed up, and running costs were higher than they should have been. **Our approach.** No pipework was replaced. We rebuilt the manifold arrangement, fitted actuators per circuit, balanced every loop against the original design flow rates and installed Heatmiser Neo zonal controls with a stat per zone. Each circuit was flushed and pressure tested as part of the works. **The result.** Even temperatures across the ground floor and a noticeably lower flow temperature required to hold them. This is the most common problem we are called to on other installers' systems, and it is almost always a balancing and control issue rather than a pipework fault. It falls under our [fault diagnosis and repair](/services/fault-diagnosis-repair) service. 1 working day on site South Manchester, M20 ## New build pipework designed around a heat pump from day one ![Underfloor heating pipework laid and clipped ready for screed on a South Manchester new build](/assets/ufh-pipes-laid-BF8LRoSp.jpeg) **The brief.** A self build where the client had already committed to an air source heat pump. The underfloor heating needed to be designed for a 35 degree flow temperature rather than retrofitted to it afterwards. **Our approach.** Pipe centres were tightened to 150mm throughout the living spaces and insulation was specified to sit ahead of the minimum, so the design could carry the load at 35 degrees. Circuits were laid, clipped and pressure tested before the screed pour, and the manifold was positioned centrally to keep loop lengths even. **The result.** The heat pump runs at its design flow temperature year round rather than being pushed up in cold weather, which is where the efficiency gains actually come from. Full detail on how that pairing works is in our [heat pumps versus gas boilers guide](/guides/air-source-heat-pumps-vs-gas-boilers) service. 4 working days on site across two visits ## What these projects have in common - The emitter design comes first. Get the floor right and the heat source, whether that is a boiler today or an [air source heat pump](/services/air-source-heat-pumps) later, has an easy job. - Existing floors rarely need lifting. [Floor milling](/services/retrofit-floor-milling) handles solid substrates and low profile overlay handles timber. - Zoning and balancing matter as much as pipework. Most systems we are called to fix were never balanced in the first place. - Every circuit is pressure tested before it is buried, and every manifold is labelled at handover. For more photographs of work in progress, including milling, manifolds and overlay panels, see the [project gallery](/our-work). For the background reading behind these decisions, start with our [underfloor heating and heat pump guides](/guides). ## Want a project like these in your home?
