Great value on the water kit

I was looking for a water underfloor heating kit and compared it to a few other places. The price here, especially with the clearance deal they had, was really good. It saved me a fair bit compared to competitor sites. Delivery was free which was a bonus, and it arrived in about 4 days. The kit had everything I needed, even the manifold and a smart thermostat, which was a nice touch for the price point. Definitely felt like I got my money's worth for the quality.

Decent system, long delivery

I bought an electric underfloor heating mat for a small room. The mat itself seems good quality, and the instructions were clear enough. It took about 5 business days to reach me, which was a bit longer than I hoped since I needed it for a weekend project. Customer service was helpful when I called about the tracking, though. The price was competitive.

Good for my bathroom

I ordered a digital thermostat and some pipe staples for my bathroom reno. Everything got here pretty fast, like 3 days. It was easy to find what I needed on their site.

Hey, thinking of getting one of their underfloor heating kits for a new bathroom remodel. Anyone know how quick shipping usually is to, say, Miami?

I think they're based in the UK, so it might take a bit longer than a local store. I vaguely remember reading something about next-day *UK* delivery. For the US, it's probably more like a week or two, maybe longer.

Yeah, I ordered some parts from them last year, and it took about 8-10 days to get to California. Not super fast, but not terrible either for international.

Does anyone know if The Underfloor Heating Store offers any deals for first-time buyers? Like a newsletter signup thing?

E Elena 4 months ago
Yep, they usually do! I signed up for their newsletter a while back and got a code for 5% or 10% off my first order. Worth doing if you're buying a whole kit.

I think they also do trade discounts if you're a pro, but for regular DIYers, the newsletter is probably your best bet. Just pop your email in on their site.
