What size expansion vessel do I need for a 15 Litre water heater?
15 litre water heater – 4.2 metres of 15mm pipework. 30 litre water heater – 8.4 metres of 15mm pipework.
How do you calculate heating expansion vessel?
Expansion volume The expansion volume is calculated as follows: expansion volume = water capacity x increase in volume at average heating temperature. Example: heating temperature 90/70 °C (average 80 °C) = 2.89%.
How do you calculate vessel size?
Calculate the filled volume of a horizontal cylinder tank by first finding the area, A, of a circular segment and multiplying it by the length, l. Area of the circular segment, the grey shaded area, is A = (1/2)r2(θ – sinθ) where θ = 2*arccos(m/r) and θ is in radians. Therefore, V(segment) = (1/2)r2(θ – sinθ)l.
Can an expansion tank be too big?
What Happens if the Expansion Tank is the Wrong Size? An expansion tank that is too large for your system will still be able to safely handle the extra water. However, a tank that’s too small can trigger the temperature and pressure relief valve to open so the excess pressure is relieved.
What PSI should my expansion tank be?
between 50 and 60 PSI
The recommended water pressure is between 50 and 60 PSI. Thermal Expansion Tanks contain an air bladder which is pressurized with air, and expands and contracts to absorb the expanded water from the water heater. needed.
Is an expansion tank really necessary?
An expansion tank is always highly recommended if you have a ‘closed-loop system’ caused by any kind of check valve or pressure regulating valve installed on your house’s water supply line. However, the long-term wear and tear of this excess pressure can reduce the life expectancy of everything in your plumbing system.
How do you adjust expansion vessel pressure?
if you repressurise it and put the heating on, the vessel should pressure up to between 1.5-2.5 bar. if it goes higher, say to 3.5 bar or so, then it has lost its charge. you should pump it up to 1-1.5 bar and watch it for a few days.
Do I need an additional expansion vessel?
As we all know, when water is heated it expands and wants to take up more volume. As the system is basically a closed loop, consisting of the boiler, pipework and radiators, it is necessary to provide some space for the water to expand into. This is why the expansion vessel is required.
What kind of boiler does a Baxi expansion vessel use?

How to calculate the size of an expansion vessel?
If you are not sure which size vessel you require please see the formula at the bottom of this page. V The total volume of the expansion vessel. It is not the acceptance volume. C The total volume of water in the system (Litres). p1 The fill pressure in Bars absolute (atmospheric or gauge pressure plus 1 Bar).
Is the Baxi no quibble guarantee still valid?
Baxi are still a popular and well-respected household name name in Britain, although in the past they did fall a little behind the competition – now they’re back at the top of their game, and offering reliable products that are made to last, with a 10-year no quibble guarantee to prove it!
Is there a problem with my Baxi 105E combi boiler?
Hopefully that should solve the problem. If your Baxi 105e combi boiler is failing to provide you with hot water, or the water is only heating up when the central heating is turned on, it could be a problem with your diaphragm washer. The Fix: The diaphragm washer can be replaced using a service kit.
