Hamish Posted November 17, 2022 Author Report Share Posted November 17, 2022 Well it’s unpacked and first impressions its tiny !!! And we’ll made. I know dimensions are on the web but you can really understand it in person !! it’s a £1 coin for scale. Quote Link to post Share on other sites
stuart Posted November 18, 2022 Report Share Posted November 18, 2022 Thats why its such a good fit and at 3kw the output is great. Stuart. Quote Link to post Share on other sites
AH3000 Posted November 21, 2022 Report Share Posted November 21, 2022 That is a beautiful piece of engineering! If I'm faced with this issue in the future, this will be my solution. Great topic and responses all. Thank you. Jay Quote Link to post Share on other sites
Lebro Posted November 21, 2022 Report Share Posted November 21, 2022 Likewise, but at present my original heater is leak free, & actually working very well. When the time come I will know what to buy. Bob Quote Link to post Share on other sites
BlueTR3A-5EKT Posted November 21, 2022 Report Share Posted November 21, 2022 I do think the new heater fan is noisier in its operation than the old Smiths Grannie’s Breath heater, which was almost silent by comparison, when the blades were not scraping the casing. The increased air output no doubt has a lot to do with the additional noise. Quote Link to post Share on other sites
Lebro Posted November 21, 2022 Report Share Posted November 21, 2022 I presume you can still slow it down with the rheostat, (or other speed control) Bob Quote Link to post Share on other sites

That could be because of inefficiency in the old fan motor that could be slowed to near stop Quote Link to post Share on other sites
Lebro Posted November 21, 2022 Report Share Posted November 21, 2022 I fitted a cheap (ebay) PWM speed controller in place of the rheostat. works a treat on the standard heater, & will operate from full to completely off, so would be good on the replacement fan. Like this one: https://www.ebay.co.uk/itm/203508376829?hash=item2f620b64fd:g:jeoAAOSwpuZg2u-7&amdata=enc%3AAQAHAAABIAWz0%2Bkg%2Bjl9tvIe3105Oyhewd4ijuSOFN8WKki%2F6s%2Bxfb4nr15lKuWEE2OMfqjnFi7EmpTdUdEoLy41cx2kAtXx4AdsfPneSGSrqSJXR%2BlMjV9GNWuQVQHOcdEUpPVeWxQvMZKa74c%2FvCS5GcJTFexTcwywrGopgWcuprZD2ChA6ZVCVbgypvAyPOGl2Y3rJ1xWKLlp%2F8nawlBstwiuTRqk%2BZH46ElJu9z3Ofr537Y8f04ABMFmz7nBB6vzyU%2FHRVYcMzIitU9AYxgiRrgeWv0ZfGo2LBMo%2FBa4kD03lH8R%2BLmba%2BQcKXKyaT1wqAYaVddwzS3js0rM5%2FnkMZF7gJUizmLwBn5BBkCdwPHFKtsv%2FNWlKpK3zqsaVgM68uKerw%3D%3D|tkp%3ABFBM5pPJr5Nh Bob Quote Link to post Share on other sites

iain Posted November 21, 2022 Report Share Posted November 21, 2022 (edited) PWM does make a big difference, allowing very low fan speed. It was “brill” on the Rally last week. The diagram on the front makes the wiring very simple……even I sorted that and as Bob will testify I’m no electrician:-) Iain Edited November 21, 2022 by iain Quote Link to post Share on other sites
RobH Posted November 21, 2022 Report Share Posted November 21, 2022 Connection is not much of a problem Hamish. Red and Black - ignition switched power and earth to the PWM unit. Blue and Green respectively outputs to Red and Black on the motor. "Simples." Quote Link to post Share on other sites

Thank you do these pwm controllers need an on/off switch ? Edited November 21, 2022 by Hamish Switch question Quote Link to post Share on other sites
RobH Posted November 22, 2022 Report Share Posted November 22, 2022 12 hours ago, Hamish said: do these pwm controllers need an on/off switch ? Not necessarily - as long as the supply is ignition-switched (via a fuse), but you would have to turn the control all the way down when you don't want heat. Personal preference really rather than a technical need. Quote Link to post Share on other sites
Lebro Posted November 22, 2022 Report Share Posted November 22, 2022 I don't have one on mine, just wired via the ign, & turn the control fully one way results in no voltage going to the motor. click on to enlarge Also mounted the control "pot" inside the shell of the old rheostat Bob Quote Link to post Share on other sites
