Inadequate hot water from MEGAFLOW system

[PSG]

I have just moved to an apartment with wet underfloor heating and hot water from a 210 MEGAFLOW cylinder. The boiler is a Gloworm Ultimate 100FF (80000-100000 btu).
The problem is that at the moment (Underfloor heating is off) the system does not supply enough hot water for 3 showers. I think it should be able to cope with this.

Has anybody any thoughts/solutions to the problem?

Thanks in advance.

I think that you have not measured/calculated what volume your showers are using!

The cylinder will store about 180 litres of hot water so thats 60 litres per shower.

Even a very basic shower will use about 10 litres per minute. That only gives a SIX minute shower in your case!

I like to take a shower for about 15-20 minutes!

Thanks for the reply. What suggestions do you have to solve the problem, or do we need a bigger tank?

Check what the cylinder stat is set to. (behind the grey plastic door at the bottom of the megaflo) and check the timer settings for HW

Yes, Thanks Dave, I have already turned thermostat on tank to max and also boiler temp to max but still limited supply of hot water. It doesn't seem to get that hot, certainly I can still put my hand under it even when boiler has been running all day.

What is boiler make and model?

What is the temperature of the flow and return pipes at the boiler?

The boiler is a Gloworm Ultimate 100FF (80000-100000 btu).

The clue is in the first post Tony

Have you checked the main pump is working ok between the boiler and the cylinder? (not the underfloor heating pump)

 

[snb]

is there any water coming from the discharge pipe?

Dave, yes it appears to be running ok.

SNB, No.

Thanks for your comments so far guys, I think that I am beginning to understand the system at last!!. I have a Megaflow specialist coming on Tues to have a look.
