static caravan

We need some advice for a 12v water pump for a static caravan, to be able to pump water from a container through 15mm pipes to a gas water heater for hot water taps, sink, shower etc. There are that many on the market we are unsure which makes to go for out of Fiamma, Whale, Shurflo etc.

DC water pump for solar powered pool heater

I require a solar cluster and a small dc water pump.

The idea is to use black pipe as a solar heat collector and pump it through a swimming pool driven by the solar powered dc pump.

The object is to raise the water temperature over a period and maintain it at a higher level than normal thus extending the pool usage/ holiday season in Portugal, Algarve.

Could you recommend equipment for test purposes. Doesn’t need much lift –say 2 metres and volume throughput need not be much -say 100 galls/hr

Is that a solar powered water pump or a 12v water pump for a solar heated pool?

would 2 12v water pumps hooked into 1 line give me more head pressure than one pump?

*As per your question , you want to run the pump in parallel.
So, you will get double discharge if your piping design is suitable for parallel operation.
Flows Q1 and Q2 combine, and that is what flows through the pipe :
Qpipe = Q1+Q2
*If you want to increase the head pressure , then you have to run the pumps in series.
*You will not give more head pressure if you run in parallel.
*YOU must go through the following links for having clear idea about "pumps in series and pumps in parallel:
