BlueTooth PU-28 controller

Out early next year this is the new controller for Planar Heaters. We can’t wait it looks amazing. 

This controller comes with a Bluetooth app that mimics the screen so you can control your heater from the smartphone.  


"Usually fit Eberspachers for customers, but decided to try the Planar, glad I did"...

  • Usually fit Eberspachers for customers, but decided to try the Planar, glad I did, very nice bit of kit and runs quieter than the Eberspacher. Will now be offering these to fit from now on! Thanks

  • We love our Planar Heater, very fuel efficient and quiet! It heats out truck camper during Snowmobile season way better than propane! I will never be without a Planar Heater in any RV!

  • Big thanks to planar heaters uk first class job

  • Sharon reviewed Planar Heaters UK5 star
  • Fantastic communications and service. Owen travelled to Cornwall to carry out fitting for us and certainly knows what he’s doing. Very professional service and we're absolutely delighted with the heater. Bring on winter!

  • I have to say we've just had fantastic service from Paul and Owen at planar heaters UK. We had an older heater that didn't have the ventilation function in its firmware which we sent back to be updated. We sent it on Friday and was back in our hands by Tuesday updated! Couldn't have been simpler. Can't fault the after service. Highly recommended.

"Our only regret is not getting one fitted sooner"...

  • Maria reviewed Planar Heaters UK5 star
  • Had our Planar heater fitted by Andrew Dyer approximately 3 months ago , the heater is excellent ,heats up quickly and quieter than expected having heard other models. When it gets to required temperature the heater slows down and is barely audible even during the night time. We ran ours constant during a weekend camping and did not see any significant drop in fuel level in our T5. Our only regret is not getting one fitted sooner.

  • After extensive research into types of van heating I settled on a diesel heater. And after yet more extensive research into diesel heaters I settled on Planar. A high quality good value product backed up by Owens knowledge and top notch customer service. Being a novice to fitting one of these I had more than a few questions which were always answered clearly and quickly. Couldn't recommend highly enough!

  • Just completed an installation of a 2kw Planar heater in our Westerly GK29. A bit daunting to begin with but surprisingly straightforward once a start is made. Of course Owen is always on hand to help out too.
    It's all up and running now and we're extremely impressed with just how quiet it is and how effective at heating the yacht. Nothing like warm air billowing out of the companionway as you're sailing along! A fantastic bit of kit at a fraction of the cost of the bigger name brands.

"Great product, great advice and at a fraction of the cost of comparable alternatives"....

  • Picked up a 4kw heater direct from Owen, for new installation on our 31ft Moody. Owen was super helpful with advice and tips for self installation. He was happy to swap controllers as I wanted the basic rheostat type, I chose main tank dip pipe installation and bought the ss mounting plate which makes mounting the heater relatively easy.
    I chose to mount it high in the cockpit locker, having glasses in a couple of battens to mount the plate on. Exhaust taken through the transom, although I didn’t use the planar skin fitting on account that due to the angle of the transom, water collection could be an issue. I insulated the exhaust using fibreglass tape, which seems to have worked ok.
    Wiring is dead easy, plug and play as described, but I had to extend the control wires, however there is an extension available if you prefer. The silencer works well.
    Fuel pick up, pump and plumbing easy enough from our plastic main fuel tank.
    I decided to buy silicone coated spiral reinforced heating duct - very easy to install and very robust, being able to withstand an accidental load (the duct runs through the internet lockers). We have two outlets - heads and main cabin (another for the fore cabin maybe over next winter). Insulation installed in the deck locker (made big difference).
    Result - quiet when all pipe work connected and the 4kw capacity is probably over the top ... positively TROPICAL.
    Great product, great advice and at a fraction of the cost of comparable alternatives.
    Thanks guys.
