Hot water cylinder size

Question

Is an 80 litre cylinder big enough to provide hot water to two bathrooms?

James · Accepted Answer

This Entirely depends on usage and reheat times of the cylinder .  You wouldn’t fit a small cylinder from new with two bathrooms. I’d fit at least a 150l cylinder with a fast recovery heat exchanger inside if it’s an indirect type. If it’s a direct type then 200l

Nick · Answer

It would all depend on how many occupants there are in the property but ideally you would want 150L minimum to avoid running out of hot water.

Chandan · Answer

standard allowance should be made of 45 litre per occupant.
45 litres + one of occupant 
A manufacturer produces a range of 90 to 300 litre indirect domestic cylinders

Marc · Answer

No it isn't  I would be looking  at 150 liters you will run out of water with 80 liter cylinder

Ethan · Answer

I would recommend around 200 litres or more, as 80 litres would barely fill a single bath.

John · Answer

Not really. Typically 50/70 litres of hot water per person per day, so add up number of occupants to calculate volume required. Normally I provide 250+ litre cylinder for 2 bathroom homes

Yes 80L is a little small, 120-150 is what would be recommended. It does depend on how many people use the 2 bathrooms and whats in them both
