excellent

product arrived well packed and in good condition, exactly what I wanted. All I had to do was fit my old plug and install in my hot tub. Slight alteration to base centres, but is working perfectly.

Very happy with part and help

I told my local hot tub company of the leak in my hot tub pump and their suggestion was a new pump. Hot tub diy on the other hand supplied a new wet end and advised on fitting via email. I have successfully fitted it at a fraction of the cost that my local company would have charged.

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

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!
