This job was in a large house which had two open flued water heaters on the 1st floor providing hot water to the bathrooms.

Our customer wanted the old gas appliances removed for safety reasons, and also desired a mains pressure system to feed his new baths and showers, instead of the noisy and unreliable pumped system.

We recommended a DualStream accumulator fed unvented system.  The accumulator (which boosts the available water flow rate in the house) was fitted in one airing cupboard, and a 300 litre unvented cylinder was fitted in the other.

The accumulator fed system discharges water at an enormous flow rate into the showers and baths. 

In fact, it quickly exposed a faulty plastic pipe joint fitted by another bathroom installer.  After a quick pop up the system was fully operational.

The new system was adapted to run off a pair of existing Vaillant open vented Ecomax Pros in the basement.  One of these was not working but it was a simple arcing electrode fault. 

We rewired these units to work with the Honeywell Hometronic radiator management system, now our customer has full control of 16 different zones of heating.
