Heat2Neat Pump Plate Set

Anyone who has fitted an air source heat pump knows the back-of-unit finish can be the bit that lets the whole job down. Ragged core holes, lagging that sags the moment you walk away, and a gap round the pipes that the wind finds within a week. The Heat2Neat Pump Plate Set is aimed squarely at that problem. It is a patented external wall terminal that gives primary pipework a clean, professional entry and exit point, and it was developed by people who have spent years doing this on the tools.

Each set contains two modified PP plastic plates and two 400mm lengths of 19mm pipe lagging. The plates are UV-stable, so they should not go brittle or chalky after a few seasons of sun on a south-facing elevation. Lagging is rated at a thermal conductivity of 0.04W/mk, and the whole assembly copes with temperatures from -20°C to +80°C. That covers a frosty January flow and return without any drama.

Where the Heat2Neat Pump Plate Set Earns Its Place

The plates suit both vertical and horizontal pipe layouts, which matters because heat pump installs rarely follow a tidy textbook arrangement. Whether the pipes drop straight down the wall or run across it, the plate sits flush and gives you a neat termination point. You get a finished look in domestic properties and on commercial jobs where the client will actually inspect the work.

Fitted with a good weatherproof sealant, the plates create an airtight and watertight seal where the pipework passes through the wall. That is the real value. A sealed penetration keeps draughts, rain and the odd curious insect out of the cavity, and stops warm internal air leaking out around the pipes. Sealant is not included, so factor that in when you load the van. Use a high performance external grade rather than whatever half-used tube is rattling around in the footwell.

Choosing Between 28mm and 35mm

The set comes in 28mm and 35mm sizes, so pick the one that matches your primary pipework before you order. The 28mm version suits the smaller domestic systems; the 35mm is there for larger runs where the pipe diameter calls for it. Measure the pipe, not the hole, and check the lagging allowance as well. Ordering the wrong size is an easy mistake and an annoying one when the wall is already cored.

Saving Time on the Heat Pump Install

The layout of the plates is designed to slot in smoothly with compatible pump systems, which cuts down on the fiddly cutting, packing and making good that normally eats into the end of the job. Less faff behind the unit means less time up the ladder, and nobody has ever complained about that. Because the lagging comes cut to length in the set, you also avoid the usual lottery of trying to bridge the gap with offcuts that never quite meet.

Heat2Neat is built for long-term external performance, so it is not a fit-it-and-forget-it-until-it-fails sort of product. A cleaner termination also helps the system perform as intended, as properly lagged and sealed pipework holds heat where it should rather than giving it away to the cavity. If you fit heat pumps regularly, a few sets in the van will pay for themselves in tidier finishes and fewer callbacks about gaps and draughts.
