Perfect for heating your wooden hot tub
Saturday, 7 October 2017  | 

I've got a 2.0m diameter wooden hot tub (wood fired) which equates to just over 3000 ltrs. Bought this kit to (a) add filtration and (b) to supplement the wood stove to keep water at temperature over night. The kit has everything you need to complete the install (I had to order a bit more pipe given the size of the tub) and was completed in one weekend. The heater is perfect at keeping the tub at temp. and will even heat from cold in about 24 hours. Excellent bundle!
