Honeywell Home offers 4,000 water and heating products, amounting to a wealth of coordinated, easy to use system solutions.

Our product portfolio includes pressure reducing valves, thermostatic mixing valves, filtration, backflow prevention, check valves, pilot operated valves and balancing valves.

Whether your requirement is to ensure water quality, constant supply pressure, safe temperature delivery or to save resources, Honeywell Home has the solution for you.


As part of our commitment to our customers, we offer a free Technical Support Helpline which is staffed by Engineers who are very experienced in all aspects of Honeywell Home Water Control products and their applications.

We have a team of engineers who are totally dedicated to this task and others who may be called upon during the peak periods. We do realise how frustrating it can be for our customers to keep getting the engaged tone and we endeavour to deal with your enquiry as promptly as possible.

Many of the calls that we get cover the same subjects. We have therefore produced a list of frequently asked questions, which will be added to our site at regular intervals.
