As gas temperatures continue to drop, more water is condensed out and the boiler efficiency increases dramatically down to about 80˚F (27˚C), which is the boiler EWT at which the boiler is rated. If the heating water system cannot deliver 80˚F (27˚C) water back to the boiler; the boiler will not operate at it's rated efficiency.
I have an Ideal Icos HE18 boiler, the status screen shows C which means it is operating normally with no fault but we have no central heating. Hot water is still working fine. We had a very short power outage yesterday so I don't know if that has anything to do with it but I've checked the trip switches and everything looks fine.
I turned up the hot water valve right off the boiler to max. Inside the transformer box there are 3 dials. One says HI, the other LOW and the third says DIFF. The HI and LOW are both set to 160 degrees. DIFF is set at 11. The boiler pressure/temp gauge reads 200 for temp. I've insulated the hot water pipes as far as I can go.
Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers. Regardless of boiler type, water quality is a critical aspect of implementing and operating an efficient steam

We recommend that you install either a system or conventional boiler with a central heating output of 35 - 42kW. A system boiler includes a hot water storage cylinder, whereas a regular boiler includes a cylinder and cold water tank. A hot water cylinder can supply enough hot water for multiple taps, showers and baths without a loss of pressure.
Since everyone's hot water demands differ, you need to choose a boiler with the appropriate output that will satisfy your needs. Usually, the more occupants in your home, the higher boiler output is needed.

How to properly size a residential hot water boiler and radiators. John White, Energy Marketing Service : A properly designed and sized hydronic heating system will insure your comfort and save many dollars on installation and operating costs. There are a lot of internet sites offering boiler sizing information.
Hot water heating is getting more and more popular because it's comfortable, quiet, steady and doesn't kick up airborne dust. Both infloor heating and hot water radiators are sometimes called "hydronic heating" systems and both these options make people feel warmer at lower room temperatures than force air systems.
Now, combi boilers are considered high-efficiency water heater and central heating units, which means that they can both heat your home and provide hot water, without the need for a separate water tank. However, combi boilers are prone to the common problem of causing the hot water to go cold or lukewarm and then back to hot again.

Boiler horsepower (BHP) is a measure of boiler energy output. One boiler horsepower (from and at 212 °F): † BHP = 34.5 lbs/hr † BHP = 33,472 Btu/hr † BHP = 9.8 kW † BHP should not be confused with other horsepower measurements. Boiler Trim: Accessories added to the boiler, such as auxiliary low water cutoff, special tappings, special gas

installation, and inspection of steam heating boilers, hot-water heating boilers, hot-water supply boilers, and potable water heaters intended for low-pressure service that are directly fired by oil, gas, electricity, coal, or other solid or liquid fuels (2). These are steam boilers in which the steam
Then, to calculate the output on a hot water boiler, multiply its efficiency rating by its listed input rating for the actual Btu output of heat. An example of a medium efficiency boiler. Of course, this is a very simple way to look at efficiency - but actually, it is more complicated.
The input is also used to determine the efficiency of the boiler for example; a boiler with an input of 150,000 Btu/hr and a gross output of 135,000 would have an estimated combustion efficiency of 135,000÷150,000= .90×100=90% eff. Next we have the boiler output, which can be listed in several ways.
preheating water heater using 24 volt PV solar panels and a 24 volt DC element.
Plus location is a major determinant. So if you are designing a home around hot water fin tube baseboards, use this (if at all) only as a loose guide. Assuming a nominal 450 to 550 BTU's delivered per foot of properly installed fin tube, my guess yields between 25 and 30 output BTU's per square foot of heated floor space.
If you've got a condensing boiler, you may not be getting the full energy savings. Follow our guide to correctly set your water temp for the best efficiency.
First, you should understand what a hot water radiator is and how it operates. It is actually very simple. This kind of radiator heats their contained water continuously from a central boiler. It will get very hot, but never reach a boiling temperature. Water is pumped from the heater to all hot water radiators in the house. Only once they have
output versions of 20/24, 25/30 and 30/34kW as mixed unit for heating and generation of domestic hot water and of 16, 24 and 38 kW as system boiler for only heating Additional energy savings by high efficiency pump (in some countries)
KompareIt says that steam boilers running on oil have a minimum AFUE of 82%. A steam boiler running on gas, meanwhile, would have a minimum of 80%. Hot water boilers have a minimum of 82% for gas models and 84% for models that run on oil. Energy.gov says boiler vs. furnace energy efficiency can also be compared by noting certain equipment features.
Indirect water heaters do not have their own heating source, but instead use the hot water from the boiler of the house heating system. The hot water from the boiler is circulated through a submerged heat exchanger in the water heater tank. When used in conjunction with a high efficiency boiler, this is one of the most efficient ways to heat water.
Six years ago, I nervously installed my first hot water heating system fired not by a boiler, but by an ordinary gas-fired storage water heater. It went in easily, worked well, and was cheap. Since A good rule of thumb is to lower the output 10% for each 10°F drop, so 140°F water would require about 40% more baseboard than 180°F water.
Ask This Old House plumbing and heating expert Richard Trethewey helps a homeowner install an indirect water heater onto an existing steam boiler to boost the amount of hot water in the house.
Hi . If you are looking to fit a combination boiler i would recomend a higher output boiler about 27-30kw the reason being the hot water flow is greater the higher output the boiler. if you are fitting a standard system with a cold water storage tank, or a pressurised cylinder a 24kw would be sufficent.
The coal hot water boilers from Keystoker make for a powerful heating option to use in your home, or commercial building. Using anthracite coal to burn, or oil if you purchase a dual fuel kit, this coal burning boiler can produce anywhere from 85,000 to 528,000 BTUs.

Proper hot water boiler sizing installation, you do not need to do a room-by-room heat loss, but instead an envelope heat loss. Then, choose a boiler using the DOE output. There are plenty of wrong ways to pick a boiler, like copying the size of the existing boiler, looking at the amount or type of radiation, water volume, BTUs per square
The minimum AFUE rating requirements for boilers varies based on the type of fuel and the heating medium used. As of September 1, 2012, all boilers manufactured have the following minimum AFUE ratings: 82% for a gas-fired hot water boiler, 80% for a gas-fired steam boiler, 84% for an oil-fired hot water boiler and 82% for an oil-fired steam boiler.
