We live in a new build and have a 150l unvented tank attached to an Ideal Logic Heat H15. The house is 4 bed, approx 1500 sqft and has 3 toilets, 1 shower and 1 bath. We don't have excessively long showers, maybe 20 minutes in total for both of us. Sometimes we can get 2 showers but we rush through to make sure we don't run out of water.
We had a plumber come out under warranty and here are his findings - we need to understand if this is acceptable
max flow rate 9.5 lpm @32.5 degrees
Usual flow rate 8.5 lpm @32.5 degrees
I need to understand what the ratio of cold to hot water is to achieve 32.5 degrees - i.e. if the tank is roughly 60 degrees, would that mean we use 55/45 hot and cold, so effectively we are using 4.5 lpm hot and 4 lpm cold, meaning we should empty the tank in 33.5 minutes (150/4.5)
Ideally we would like to have a warmer shower but I can't as we don't have the water capacity.
