Hi,
I recently moved into a ten-year old house. The hot water of the shower
worked fine in summer. However, when the outside temperature begins to
drop down around 30, the hot water in the shower does not seem to work.
The faucet water is hot, but the shower water can only reach warm level
at the best. The heating system is in the garage and it is a new system
with only 5 months on it. Two bedrooms have shower, it seems both
showers have the same problem. The shower has one bolt - turning to the
right is cold water and turning the same bolt to the left is the hot
water. Would anyone please give me any hint on what might be wrong with
the hot water in the shower? Thank you very much. - Lily

If they're electrically heated they will not give as much hot water in
winter since the incoming water is colder. However you should be able to
get hot water from them, albeit at a pitiful trickle.

If they're mixer showers supplied off a combi boiler then the combi may be
misbehaving. How hot is the water going to the mixer valves (feel the
pipes)?

I don't know where you live, but it isn't anything like 30C for about 364
days of the year round this way!

It's probably just colder water entering the house. You need to turn down
the flow rate of the shower so that the heater can keep up without going too
cold.

I can't tell what type of shower you have. "Bolts" are not something I
associate with shower controls. However, any instantaneous heater will have
this issue. This includes electric showers and instantaneous type combi
boilers. They can only produce a certain amount of hot water. If you ask for
more, it will go cold.

Of course around this time of year the temperature is starting to dip
to about 30F in most of the country!

youd need to tell us what type of system youve got to get anything
specific. Plain boiler or combi, hot water tank or heat store, electric
or mixer shower or a start.

I have showers which run off combi boilers and thermostatic shower
valves, (i.e. a tap which controls the flow, and a tap which controls
the temp). When fitted, I often find that the temperature tap on the
shower is set so it is blocked, (physically by a stop under the cover),
from allowing more than a certain amount of hot water through, so the
shower doesnt get hot enough.

I can usually solve it by taking the temp tap op, and rejigging how it
sits on the cogs, or similar. It takes a bit of thinking about to get it
right g

Hope this helps.
