    Megaflo

    Hello, I'm not a plumber, but I've been looking into this. I'm assuming your cold flow is the same? I just tested our water and the pressure dropped from 3.5 to 0.4 bar as soon as you turn the taps on. So the flow is poor. What size pipe do you have to the megaflow, and what size...

    Best heating system for low pressure mains?

    Right, I've just done a test (as you can tell i'm clearly not a plumber) but know about flow rates and its relationship with pressure. I'm not sure if the test is any use but i'll explain what I did and maybe somebody can use the information and help. I tested the static pressure. (by...

    Best heating system for low pressure mains?

    I've just had a look at the link. Can this be used in conjunction with a normal cold storage tank? It says upto 60l/minute at 4 bar pressure for the biggest unit. Providing its safe to put before an unvented cylinder. (I can't see why not) Any idea of the cost of the boosters?

    Best heating system for low pressure mains?

    It is going in a wet room. Thats the main head, there will be a "normal" sized shower head as well. Waste will be a long grid. I'm not sure on the waste pipe yet. But I don't think 42mm will be sufficient. The bath can fit 2 people in. Although I doubt the Mrs would happily bath in my water...

    Best heating system for low pressure mains?

    I see your point and appreciate the advice. I'm not too concerned about the cost, I/we only take a bath once in a while and it might as well be a nice experience. A very rough calc i've just done would say its going to cost approx 50p per bath. The spec says 460 litre. I don't know how full that...

    Best heating system for low pressure mains?

    Hello, I'm in the middle of my house renovation, at the moment we have average/poor mains pressure/flow. While building an extension we had to "move" the mains supply, it is lead and kinked/damaged, so I am hoping this is partly the problem, and it will be solved when we run a new large bore...

    Electric or water under floor heating, + air con, radiators.

    Hello, I'm just finishing an extension on my house. The room in question is 10 meters by 4.5 approx. It has 3 large windows, (2 velux) Bifolding doors on 1 wall and another door. While all are new and "A" rated, I'd assume a fair amount of heat loss. There are 25 meters of external walls...

    Most powerful shower

    I'm assuming dynamic pressure is the pressure with taps etc running? Can I test this myself by using a normal pressure gauge then running the taps etc.

    Most powerful shower

    I did look at this, but I was thinking it might be a statement as a "min" to make you buy it thinking it'll be ok. Most shower heads say the same. I don't know the actual pressure, I've never measured it, but will before I make my final decision. It must be over 1 bar as it had no problems...

    Most powerful shower

    Hello, I'm starting my house extension on Monday, which includes extending the bathroom. I currently have an electric power shower. (Mira 10.8kw) and to be honest its pretty lame. At full power it needs to be around 80% heat on the dial so I'm thinking its a limitation of the shower rather...
