HOT WATER FILTER KIT

Boiler & Central Heating Protection

Whilst many people filter their cold water, hot water is often overlooked. Over time fine sediment such as sand, silt, dirt and rust can build up in your hot water system, which reduces heating efficiency, shortens the lifespan of appliances and means you use more energy to heat the water. Considering energy prices and the average cost of replacing a hot water heater being in excess of £1,200 it makes sense to install a hot water filter to protect your home. Our low cost hot water filter kit can be easily installed on either 15mm or 22mm pipework and once installed, requires very little maintenance.

Low Cost Replacement Filters
We use industry standard components to build this kit, keeping costs low without compromising on quality or performance. The high temperature sediment filter included offers a long lifespan of up to 12 months, giving an average cost per day of just £0.02.

How Often Do I Need To Replace The Filter?
It is recommended to change the filter once every 6-12 months.

There was an issue with the water softener I ordered initially, but then following communications made the replacement process quite pleasant. Happily recommend this company. Thanks to Becky for working with me. Great follow up support 😊😊😊

 Trustindex verifies that the original source of the review is Google. First time using this company and product and i wasnt dissappointed. Communication was easy and quick resulted in an easy order and now having fitted the filter i can say its a great product easy to install and appears good quality apart from the four mild steel bracket screws stainless would have been better considering the environment these are fitted. All in all, very pleased and would highly recommend .

 Trustindex verifies that the original source of the review is Google. Excellent local company and genuinely lovely people to deal with. Really helpful and knowledgeable, with great advice about my water softener and the correct salt to use. They even gave me some resin cleaner at no charge, which was a very kind gesture. Fantastic friendly service and I’ll definitely be returning for my salt in future. Highly recommended.

 Trustindex verifies that the original source of the review is Google. Excellent service.  Product proved my softener was not working as it should.  I fully serviced it and cleaned with Resin Clean returned to service and it is now working as designed.  Very pleased.

 Trustindex verifies that the original source of the review is Google. If you're thinking about a water softener then i HIGHLY recommend Ultra Soft Water Softeners Ltd.

Great softeners and exceptional customer service. The water softener I bought needed some adjustments with the installation setup where I supported throughout. The customer service is honestly next level. I had countless calls with Becky Gillett, the Sales Manager, over a period of months to get to the bottom of it. She was incredibly patient with me, staying on the phone and doing video calls to walk me through the programming instructions step-by-step while I changed the settings and ensured all was installed correctly.

All the staff here have been great, but Becky really stuck with me from start to finish to make sure it was sorted and working well. It runs like a dream now.

HIGHLY recommend them!
