Servicing your Unvented System

Regular servicing and maintenance is important to check operation of controls and components, also to ensure your system as been installed to comply with Manufacturers fitting instructions and G3 Building Regulations, running efficiently and safely.

As per Makers recommendation, your unvented cylinder should be serviced yearly. We recommend this be carried out during the summer months to ensure you are up and running for the winter periods. We offer reduced service rates to carry this out during May to August.

"Highly recommend. No heating or hot water 3 days before Christmas due to boiler failure. Attended same day and replacement boiler installed the following day. Fantastic service."

EHV Customer

"We have been fortunate to have been able to access a range of services from EHV over a number of years. Their input has included difficult access problems, for example finding and accessing main water pipes for a new build downstairs toilet extension; removing and installing a new gas boiler situated in the loft."

EHV Customer

"EHV renovated our upstairs bathroom, efficiently sourcing chosen fixtures, fittings and heating. Their workforce including plumbers, tilers, electricians, are of a high calibre and expertise. The standard of work and finish has always been excellent, and they always protect the surroundings, and remain careful and courteous throughout."

EHV Customer

"James was very professional and very informative. Although he couldn’t solve the entire problem ( low water pressure) he has made things better, and also enabled me to communicate more effectively with Thames Water."
