I've been considering using them for heat, either primarily or as an assist to my 25 year old gas boiler for a forced hot water radiator system in a reasonably well-insulated 100 year old house. I pay about $1.50 per therm for gas, and about $0.11/KWH for electricity.
Next to forced-air heat, a boiler-and-radiator system is the most common type of heating system in cold-winter climates. All boiler systems use hot water to heat the home. There are two main types of boilers—steam and hot water (also known as hydronic)—and many more types of radiators or heating appliances, the units that transmit the heat into the rooms.
How to Choose a Residential Gas Boiler. Gas boilers use combustion to provide heat to your home, or water through a series of pipes that run outward from the boiler. Most gas boilers utilize
Here's a list of ideas to get your gears turning, starting with Johnston's suggestions for how to save green by going green with boilers and radiator heating systems. Install a High-Efficiency Boiler— The energy efficiency of boilers and furnaces is measured by assigning each unit an AFUE (annual fuel utilization efficiency) rating.
Boiler thermostats set the temperature of the water that will be pumped to the radiators. The higher this is set, the more energy will be used and the hotter your radiators will become. As long as you have room thermostats, you can set the boiler thermostat reasonably high to make sure that enough heat is generated.

Most flats and average sized home with around 10 radiators, will need a boiler than a 24kW to 27kW would be fitted. For a medium sized home, around 15 radiators then the 28 to 34kW boiler will be fitted.
Ideally, your boiler's pressure should be set at the 1.5 bar. If it is below 1, your boiler will not be able to function properly. Low boiler pressure can be caused by issues such as a system leak, recently bled radiators or a failed component or seal.
A hot water heating boiler may not turn on immediately when you turn up the room thermostat: if the water temperature in the boiler is already above the aquastat's cut-in temperature the circulators will send hot water to the radiator and the boiler will turn on later when its temperature is dropped by returning water from the cooler radiators
We've got a combi boiler and it doesn't seem to warm the house up much at all. Currently the radiator temperature on the boiler itself is set to 52 degrees - is this too cold? We don't have thermostats or anything like that (tiny one bed flat) and I've bled the radiators so this seems like the major factor.

Steam radiators are connected to a boiler given the task of heating up water. The boiler heats water until it forms into steam. The boiler heats water until it forms into steam. The steam then travels up through the vertical pipe to the radiator where the thermal energy is given off through the fins.
Boiler Piping Flow & Pipe Sizing - It is very important this is correctly done as too much flow rate reduces efficiency as described above and it can have detrimental effects on the boiler. All manufacturers of cast iron boilers want the Delta Δ T of the boiler with a certain range. Some are 20°F while others are 30°F.
instead of boilers and how I answer each of them. Myth 1: Water Heaters Can't Produce Hot Enough Water Typical boiler systems use a design temperature of 180°F or higher, which produces scalding hot surface temperatures at cast radiators and convector units and is too hot for radiant floor applications.
The boiler uses gas to heat up water. An electric pump in the boiler pushes the heated water around your radiators and to your hot water tank, if you have one. As the water flows through the central heating radiators, it gives off some of its heat to warm up your rooms. The heated water also flows to your taps and showers when you switch them on.
Once a boiler has heated system water, the heat is delivered to heat emitters, such as panel radiators or baseboard panels. Combi boilers heat water for domestic service through a similar process. Upon a call for hot water, demand is received by a flow switch adjacent to a combi boiler's flat-plate heat exchanger.

All you need to do is provide a Radiantec mixing valve to step down the temperature of the water to the radiant circuits. You mix hot water from the boiler with return water from the floor to provide a lower temperature. Can I use my existing boiler for both radiant heating and baseboard radiators? Published July 8, 2015 You mix hot
Another defining characteristic of steam boilers is the type of radiators it uses. Occasionally, homes with steam boilers will have baseboard heaters, but most of the time, freestanding cast-iron radiators in each room indicate a steam system. Baseboard Boilers (Forced Hydronic)
About radiators. Radiators as the name suggests not only give the radiant heat, they deliver most of their heat through convection. However air warmed by the radiator naturally rises and cools down, as a result the warmed air circulates and the space in the room is warmed. In a boiler there are several symbols that are found on Vaillant boilers
Radiators; Bathrooms; People in the home. However, there are some general guidelines which you can base your research on; we've put together this rough sizing guide to help you. Best Boiler for 2 Bed House. A Combi boiler with an output between 24-27kW is best suited to a small terraced house, flat or apartment with 1 or 2 bedrooms.
The term "boiler" is a carryover from the past when steam boilers were common, which boiled water to make steam. Today's boilers are water heaters and typically use natural gas. Most can heat water in a range from 145-190 degrees, depending on the radiation system.

Cleaning radiators, fireplaces, and boilers (furnaces) are clearly tasks best done in the summer. Fireplaces can be a slog, but the rest are five-minute wonders. Item Cleaning Method Radiator Frequently vacuum the central grooves with the crevice tool of your vacuum. To periodically dust the back, lay a cloth on the floor under the radiator, 
When the water reaches a high enough temperature an electric pump moves the water from the boiler through the outlet to the rest of the house to run through different types of radiators installed in your home. The inlet takes in cool water from the home to be warmed up by the boiler before being sent out once again.

If you have steam heat, each of your radiators will have either one or two pipes. All steam radiators take advantage of gravity to get the condensed steam (called "condensate") back to the boiler. The key to making it all work is to keep the system pressure low.
The boiler is at the heart of every radiated heating system. It's responsible for producing and sending hot water (or steam) to the radiators that then distribute heat throughout the entire home.
The Electric Heating Company recognise that "Time is Money" and as such have developed Electric Boiler and Cylinder Packages that incorporate all the necessary components (with the exception of radiators, radiator valves and pipe-work) for a complete Electric Heating & Hot Water system.

Hot water heating systems need a little maintenance, like venting the radiators and draining the boiler, to keep things running efficiently. Gravity and hot water furnaces are not often installed in new homes today, but similar systems with the old cast-iron radiators throughout the house were fixtures in homes built around 1900, and some of 
Steel panel radiators are an efficient form of heating that requires a fraction of the wall space of traditional baseboard. Pensotti Steel Panel radiators are ventil style, this means that both the supply and returns are on the bottom of the radiator which allows for reversible mounting.
Boiler & Central Heating Stoves. A boiler or central heating stove can provide heat to both the room in which it is installed and to radiators and water within the heating system.
