but lets not talk about Assange...that would make the UK worse than Russia right! Oy vey

flow rates are limited by pipe diam and the number of draw points. Also a combi has a "theoretical" output as its based upon temperature rise but will always have an "actual flow" rate at whatever temp it happens to be (restrictions on the internal path through the boiler heat exchanger. You...

LPG and a continuos water heater...all problems solved

This is not the beginning of the end, but the end of the beginning. The moral collapse of the west is now complete and the collapse of the colonial domination is speeding up with each passing day. The financial collapse of the west has already occurred So, time to consider moving to parts of the...

for this calculation there is a limited range of temperatures. The heating flow will be at best 70 degrees...so the volume (not mass) is negligible for calculations https://www.engineeringtoolbox.com/cubical-expansion-coefficients-d_1262.html

What is the mass? well what is the volume! interchangeable....So a volume (which = a given weight) flow at a speed = mass flow rate...the mass(volume) how do you measure the flow rate...or is this just another guess?

why don't you actually measure the pressure at each rad? Simple pressure gauge and a few push-fit fittings will give you the definitive answer

but a given volume has a given mass at a given temperature so refer to whatever you want, there is a fixed correlation play with this chart to see https://www.engineeringtoolbox.com/water-density-specific-weight-d_595.html

Rinnai continuos water heaters have 13:1 modulation, can detect incoming water temp and modulate accordingly so the gas/lpg is the boost.

I used one of these. https://www.screwfix.com/p/tubfix-bath-front-frame-kit-1500-1800mm/499gp

How do you factor in the air volume changes in each room when you undertake heat load and heat loss calculations for central heating emitter size at a given delta T?

the principle is scientificality sound however, the installers are not. I paid for full surveys from "experts" and they arrived with a hand held temperature and humidity sensor and a tablet to enter data. I asked how they were going to measure airflow changes rates and internal pressures in each...

Capita gas fee payers cannot ever be in breech on BC regs as they self certifiy that they can't breech regs so no regs have been breeched. Even if you could argue this point in a court of law, it would still remain the property owner who is responsible, not the capita gas man

complain to capita plc? for what purpose? Might as well complain to Tu holidays, they have the same statutory and regulator powers...NIL...

If your fan can expel 100m3 of air per hour and you only have 80m3 per hour able to come into the room to replace it, it creates an imbalance in pressure and through-flow is not achieved.

so logic says that if water is coming from an overflow pipe then its dong its job so now the question is why. What stops the water from continually feeding into the tank? a simple ball valve. What can go wrong with a ball valve? well if the arm is allowed to move freely to close the apature then...

I'll take that bet with you! £100?

I was being facetious FFS

if it is a registered (booked) asset of Ltd company AND it has appreciated then on selling the business it would be a capital gain. With a single shareholder business then he could sell it to himself at a loss. Guess you have never used Ltd companies for the purpose they were designed lol
