Hello, hope you're all enjoying the bank holiday weekend.
I have a customer with a Dedicated Pressure System (DPS) Heat Bank System (Thermal Store).
If they run one bath/shower, it's fine. If they try to run two at once the water at both is barely even warm.
I know the house has been extended by about 50%, adding an additional bathroom that the thermal store was not originally installed to cover.
I'm unsure if there's any fault involved, or if the flow rate of two showers at once is just exceeding the max flow rate that the thermal store heat exchanger can keep up with. The thermal store capacity is 150ltrs, my gut feeling is this just isn't up to the job, though i guess there could be a few issues with it causing it to not perform at full spec (pump running slow, blocked heat exchanger etc)
Has anyone got much knowledge of these and can advise whether it's worth investigating or if it's just not big enough?
Thankyou in advance for any help
