What is an unvented hot water system?
An unvented hot water system connects directly to your mains water supply, delivering powerful, consistent hot water to every tap, shower and bath in your home - without the need for a cold water tank in the loft. If you’ve ever been frustrated by weak water pressure or waiting for the tank to refill, an unvented system is the upgrade your home has been waiting for.
At MJW Services, we supply and install unvented hot water systems to the highest standard - advising you on the right system for your property and ensuring everything is fitted safely, correctly and built to last.
