Q:How many KW boiler will i need for 3 bed bungalow which will have 7 radiators about 95 sq meters of floor space

Where? how well insulated? the climate makes a difference

Q:I have an old 100 Gallon boiler that heats my house. To say the least it is less than efficient and I am looking to save some money on gas this year. I have taken the insulation in my attic from a R almost nothing to an R39. I was wondering if it would be effective and safe to put 2 (because it is so large) water heater blankets around it. Although I do appreciate opinions I would like to hear from some pros who have an experienced answer.

If the heater is designed for a blanket it may help a tiny bit on your bill to wrap it. You must examine the heater and make the decision if it is safe to do so. With the age and design of the boiler the insulation may be a waste of time though. On these old systems it may be a case of complete replacement to get any significant savings in the end.

Q:what is the purpose of a boiler?

Q:I have a generator rated 3000w/3500w surge was told that it would run my gas boiler OR TV fridge but not all. Is that right?

A gas boiler typically only needs electricity for controls and for hydronic circulators. You would generally not select a generator that is undersized for the load, i.e., better to have slightly too much generator than even a little bit not enough. A fridge has a compressor motor that may require spikes of power each time cycles on, drawing three or four times its normal operating power. This dips into the surge specification on the generator. If you're anywhere near full capacity when that happens, you could fry the generator (or at least blow its breaker). You can look at the power ratings on your boiler, circulators, refrigerator and add in the lighting loads, to see whether you're more than half the capacity of the selected generator. Rule of thumb: combined refrigerator and warm air blower would be anywhere from 800 watts to 1400 watts. If they start at the same time, you would estimate the simultaneous, worst-case, max as, say, 5,200 watts of surge and plan accordingly. Or you could buy a measuring device ('Kill-A-Watt is a popular brand) and record the peak usage of each appliance and add those together. If you can guarantee that all appliances will start at different times, then you can reduce the maximum requirement. For example, when power goes out, you can plug in the fridge periodically, when you know everything else is either unplugged or has stabilized. The overload problem often occurs with a transfer switch that simply restarts everything at the same time. You can manually shed loads by switching off some of the devices when you transfer the load to the generator, then add them individually by switching them back on.

Q:Boiler model: Q40 / 960-16-3.82 / 450 on behalf of what meaning?

960 - the temperature of the waste heat carrier, 960 degrees;

Q:i had my boilers coil clean two days ago, and the guy who did it said that the coil had a crack. Now my boiler is releasing hot water in all my floor. Is it possible that he cracked the coil, because it did not release water before the coil got clean. he said that the coil cracked because the every time the coil get clean it moves back and forth, is the true was the his fault.he works in a company and has an office in town.

It's not very likely that he cracked it, but it is possible. Just by cleaning it won't cause a crack. Now, if he drained out the water and left the gas on getting it hot, then returned the relatively cool water to the how boiler parts, then yes, it can make a crack. Those coils are generally cast iron, and VERY heavy. They don't move much if any at all. It depends on the boiler system you have. If you have the instantaneous type, I still can't see how he could have made a leak, unless he beat it with a hammer.

Q:I plan to bleed my radiators for the first time. I've read that If you have a gravity filled system the system will look after itself but if you have a combi boiler, the pressure will need to be checked after bleeding. How do I know what I have? The boiler is an HB Smith G200 Series that is about 30 yrs old. Thanks.

-Combi boiler usually heat the hot water also. So they heat the house serve as the hot water tank. - Gravity filled are just plan steam systems. All your boiler does is heat the radiators. Combi systems PSI usely goes upto 30-40 Gravity systems PSI

Q:I asked this question once already, but I guess I didn't give enough info, so I am going to try this again. Bare with me because I honestly don't know anything about this, that is why I'm trying to get info on here. I am currently looking at buying a house that is heated with a boiler furnace. There are base board vents through out the house, and multiple thermostats to control the heating in the different zones of the house. I'm not sure if this also controls the hot water, or if there is a seperate hot water heater. My understanding is that there are lines that run along the base boards, hot water runs through them and some how heats the house?!?! Like I said, I really don't know, and I am just trying to get a better understanding of this system. ANY info on them would be much appriciated, such as cost to replace them, repair them, or service them. Common problems to watch out for, how they opperate, and if it would be better than a regular furnace.

Don't buy the house!!! My father owns a heating a cooling business and I helped replace a home such as the one you are considering to buy with a regular furnace. Major costs and house repairs!!!

Q:I am having a new oil fired boiler installed. The contractor wants to install a Weil McLain WGO-6. he says the input is 175,000 BTU's and the output is only 125,000 BTU's.What does this mean?

Boiler capacity is determined on the amount and type of radiation you have installed in your home. Your contractor probably/ hopefully measured the radiation units to determine the boiler capacity. The original heat loss that was taken on your home when it was built determined the radiation units size and again the original boiler capacity should have been sized from them etc.....

Q:I have a 1400 sqft house that's 2 floors. the first floor is 800 sqft and the second floor is 600 sqft. I plan on using baseboard heat. The house is a cape that was reinsulated with R 36 a few months a go

you will need a little more information like what is your climate area (coldest temp outside that it gets) the type, style and how many outside windows,doors,the amount of insulation in the outside walls and roof,the height of you ceilings,is there a heated garage attached or not,and the best of all do you plan on getting your hot-water off this boiler and if you do is it to be a coil which is inside of the boiler or are you going to add a indirect water heater which is piped to the boiler a person could guess and say around 120,000 btu boiler but guessing is not what we do right,if you can't get your heating company to come and do a heat loss calculation on your home you might be able to take all this information that you collected and bring it to a big box store lowes,home depot, or another and they will do it for you or look up heat loss on the web
