One of the major drawbacks of most residential hot-water heating systems is the lack of control for various areas of the home, or zones. Most older systems were installed with only one thermostat and an "all or nothing" approach to heating. This means the boiler and circulation pump will either produce heat from all the radiators when operating, or stop when the thermostat is satisfied. If your basement is quite open, especially the area near the boiler, it may be possible to identify the individual heating pipes to isolate the ones going to the upper floor of your home. If the ceiling and pipes are covered or hidden inside basement or main-floor walls, access for upgrades may be very difficult. Also, if they are still the original iron pipes, it will require a skilled pipefitter to cut...
Regardless of this last point, any modifications to gas fired heating equipment such as your old boiler or a furnace should only be attempted by a licensed gasfitter. A hot water heating system is a pressurized system and homeowner modifications can be very dangerous. You may inadvertently cause damage the burner or other components when attempting to remove or replace the old refractory. These components are typically composed of ceramics or special firebrick held in place with special heat resistant mortar. Regular concrete blocks may not last very long without cracking from the heat of the flame. Also, modifications of pre-cast concrete will not be easy and may cause voids or small air pockets in the concrete, which could be a major safety hazard. If the air is heated inside a small ...
In the spring, the malfunctioning boiler was taken offline and the building's backup boiler - an original from the facility's construction back in the late 1970s - was then used to heat the pool and maintain the domestic hot water supply this summer. In the interim, the city plans to host a series of community consultations, with a focus on youth, to determine what type of activities an indoor sport field might facilitate.
He said he wants the community to know about this because 'I am kind of setting a bar, and maybe people of equal means will think of those kinds of gifts to help improve the quality of life in the inner city,'" said [John Mohan] on Wednesday. "Because we had been public about our need (for donations for a new boiler), I felt we were ethically bound to be public about the fact the need had been met. "Because of its age, we were informed it wasn't even feasible to repair (the boiler)," said Mohan. "It was something we hadn't even planned on...we weren't prepared with a back-up plan, we weren't prepared with funding." "He had already suggested a six-figure gift, so when he comes back and said 'I've changed mind', I don't know about you, but I thought it was probably going to come dow...

TENANTS at a Wolseley apartment block left without central heat for 16 days said they're relieved the 21-suite building's boiler was finally working Friday. It's exciting (to have heat back). It was getting really old without it," said Kelly Reimer, a tenant of the building, which is known as the Gloucester. "We're trying to figure out some sort of a response to what's happened and talk about suitable forms of compensation," he said.

Natural gas does not produce space heating and domestic hot water (DHW) directly. It first must go to a boiler where it is transformed into hot water that in turn is used to produce space heating and DHW. The ability of a boiler to transform natural gas into hot water is known as boiler efficiency. Boiler efficiency is a very misunderstood number and often building owners will assume that the efficiency of a boiler is what the theoretical value that the boiler manufacturer specifies (typically in the 80 to 90 percent ranee). In actual fact, the efficiency of a boiler is in the 60 to 70 percent range. This efficiency is usually referred to as "real world" or "seasonal efficiency." There are a number of reasons why the real world or seasonal efficiency is lower than the theoretical boiler...
