Frequently Asked Questions
Q.
Can accumulators be installed on 15mm or shared main supplies.
A.
Yes. Carry out pressure and flow tests and oversize the accumulator to meet demand
Q.
Can the accumulators be installed horizontally in a loft?
A.
No, this is not ideal but models up to 240 could be laid in this way but it would lessen the warranty on the vessel, installing in a loft vertically is no problem, as long as you have the usual requirements, access, light, support etc.
Q.
Can the accumulators be installed outside, in a open garage or shed?
A.
Yes, the C2 range is ideal and designed with this in mind, remember no power supply, or drainage requirements so they can go almost anywhere, basements garages etc. The pipe size can also be run in plastic from the accumulator to the house in the correct size.
Q.
Can I drink the cold water from an accumulator?
A.
Yes, ideally we recommend a separate drinking supply as requested in water regulations, but the accumulators have been tested and passed for use on potable water, and the butyl liner contains no harmful Pilates.
Q.
How efficient is the accumulator?
A.
Very is the simple answer, yes there is a carbon footprint in the production of the vessel and shipping the unit from the USA, but once installed the accumulator requires no power supply, consumes no energy and is silent in operation, there are also no on going maintenance costs
Q.
Does the accumulator improve my pressure and by how much?
A.
No, accumulators are designed to increase flow rate and stabilize pressures, although the effect of having the accumulator on the system for most people looks as if the pressure has been increased. You have a standing pressure, which is the pressure when no outlets are running and a working pressure the pressure when outlets are running. When the accumulator is linked into the system the increased flow rate helps to maintain the pressure close to the original standing pressure, for as long as water is stored in the accumulator.
Q.
Do the accumulators make any noise when in operation?
A.
No, there are no working parts within the vessel and therefore no noise issues, water at a good pressure can caused noise through pipe work if not clipped or supported but no noise from the accumulator. And with no power supply or running cost or ongoing maintenance it is both a greener and more efficient option.
Q.
I have a combination boiler and the incoming flow rate is poor, can an accumulator be used to increase the flow rate?
A.
Yes, we have many installations a month where an accumulator will be used in conjunction with a new or existing combination boiler. Carry out pressure and flow tests and then select the accumulator size required, normally a 200 or 240 models or above. The accumulator will increase the flow rate allowing the combi to run at its maximum given flow rate and not be interrupted by other cold outlets. For an impressive performance look one of the new breed of combi store boilers, that have 40,50 litres of unvented store, linked with an accumulator you get a mini Dualstream system.
Q.
I have seen other websites mentioning accumulators, why should I choose your system?
A.
