Megaflo Repairs

If your Megaflo cylinder has stopped working, developed a fault, or broken down completely we can send an emergency engineer to fix it at a convenient time that suits you. We are expert at fault finding and will make sure that your system is back operating at optimum performance levels as quickly as possible.

Our Megaflo engineers are Unvented Hot Water Storage Systems (G3) trained so you can be confident that we are competent to carry out any installation repair or servicing of Megaflo cylinders.

If your Megaflo or another brand of hot water cylinder is not working to its full performance, please call our friendly office on 020 3880 5666 for advice and an assessment.

Megaflo Installations

We recommend that your Megaflo cylinder is serviced annually to maintain optimum performance. In hard water areas, this is especially recommended because the immersion heater elements are much more likely to require descaling.

All servicing must be carried out by a competent person with the correct qualifications and certification. At Palace Plumbers, should we require any replacement parts, we?ll only use authorised Heatrae Sadia spare parts.

During your Megaflo service our G3 certified heating engineer will check the operation of safety valves, clean the strainer, drain the Megaflo unit, descale the immersion heater, refill the system and fill in the logbook..
