Diamond 500 Central Heating Kitchen Plinth Heater: Stainless Steel Grille, Under cupboard heater

This unit was much cheaper than similar equivalents - I have been impressed at the build quality, length of flex pipes and instructions.The heater works really well in 'automatic' mode, cycling on and off automatically in time with the central heating system.It kicks out an impressive volume of warm air and seems most effective on the 'low' fan speed setting, which also makes it quiet enough not to be annoying.The only thing I would say is that the vents in the trim panel have quite large slits in them - I have fixed course black filter mesh behind them so you can't see under the cupboard through the vents. This is safe to do because the material I've used does not restrict airflow noticeably and the unit does not contain an electric heater so there is no danger of it overheating.

Too noisy

Very quick delivery nice secure packaging easy to read and understand instructions easy to install most certainly does what it says on the box. Motor a little noisy but not overpowering. All in all very good value for money.

Super product. Thank you.

I installed this heater in a utility room with a volume of approx 20 cubic metres. I wanted a plinth heater with low output for a small room and this has been very effective. The outputs of other hydronic plinth heaters was too high.The first heater was very noisy: 58-60dB on low fan speed and a very intrusive whine. The product was promptly replaced and the new heater was much better: 45dB. The supplier told me the specification was 46dB, which I think is too loud for most people in their kitchen. In a utility room, with the door closed, I'm not aware if it's running or not.I liked the automatic operation of the fan when the heating system comes on, and the option of running the fan on manual to circulate air when the heating is off. The heater was significantly lower cost than other options.

Great little unit does what it should

Good heater a tad noisy but made a massive difference to the design of our new kitchen meaning we could use a wall that previously had a radiator on I didn’t know that they existed to run off central heating ordered a 2nd one for utility room unfortunately had missing parts so had to return

Excellent product, i have purchased a number of these and will continue to do so.
