The Temperature Problem /Heating and Cooling
The temperature problem of using a single heat source for both hot water baseboard heat and radiant floor heat is one that plenty of people do not comprehend entirely. It is correct that it is essential that water supply temperature to the two kinds of systems is significantly different. However, this does not mean that a single heat source cannot serve both heat systems. Misunderstanding on this issue occasionally sways people to look for other heating preferences. Slight alterations of the existing heat source for hot-water baseboard heat is all that is required to make it generate water of a correct temperature for a radiant system.
Water temperature for water being run through hot-water baseboard heat must be a lot hotter compared to the water required for a radiant floor heating system. Copper tubing is the most common kind of supply piping used with baseboard systems. The fin-kind heating components gather heat from the water passing through the copper tubing and then radiate the heat to living space. Radiant floor systems do not use fins. Plastic tubing is the most common material used to carry water in a radiant floor system. The temperature of the water coming out of the boiler and going to the baseboard units must be high, if a boiler is going to be used for hot-water baseboard heat. Nevertheless, this same high-temperature water is too hot for a radiant system. Therefore, let’s explore what can be done about this.
Radiant floor heating is believed to be a low-temperature heat, in terms of the supply water being used. A standard water heater is all that is required to generate enough hot water for a small radiant system. The precise water temperature supplying a radiant system can depend on lots of factors; however, in all cases the water temperature should be a lot lower than the water used to run a hot-water baseboard heating system. Factors that influence the temperature of the supply water include:
The spacing of heat tubing
The method of installation for a system
The kind of completed floor material being used
The heat load for the building being heated.
There are three standard kinds of categories for radiant floor systems. Type 1 systems do not need extra temperature control. Single temperature tempering is needed when type 2 system is used. Type 3 systems; a weather responsive reset control is required. A Type 1 system may be one where a standard plumbing water heater is used as the heat source. As the water heater is thermostatically controlled, that is the only heat control required. For example, the thermostat for the water heater could be set at 110 degrees and left to work on its own. This, obviously, does not apply when a boiler for a hot-water baseboard system is being used as a heat source.
A condensing boiler is another kind of heat source that is used with Type 1 systems. These boilers are designed to operate correctly with extremely low return water temperatures. This is not the case with boilers used for baseboard heating systems. Condensing boilers use low-temperature return water to condense flue gases. The heat gained from the flue gases helps to heat supply water. This is fairly different from operation of a non-condensing boiler, like the type used with baseboard heating systems.
Even if an entire heating system consists of radiant floor heating, a non-condensing boiler should not be used as a heat source. These boilers are supposed to work with higher water temperatures. If the return water to a non-condensing boiler is colder than 135 degrees, the flue gases within the boiler can condense. If this occurs, the condensation is extremely acidic and can damage the flue or the boiler.
Installation of a Type 2 system needs the use of a tempering valve. This valve has to be installed between the boiler and the radiant heating system. When a tempering valve is installed, it safeguards the boiler from low-temperature return water and provides water as a supply for the radiant system at a correct temperature. A three-way tempering valve is the easy and effective method of achieving Type 2 control. This kind of valve gives a constant, fixed water temperature for radiant floor heating, without affecting boiler operation.
How does a three-way tempering valve work? Decent ones have valves inside that keep in check sections that expand and contract to control water temperature. One port of the three-way valve supplies the hot-water baseboard zones. A second port supplies radiant zones. The third port is a bypass that permits the water temperature to be set to a preferred level. Expansion and contraction of the interior element opens or closes a shuttle valve, as required, to keep a steady temperature. A good tempering valve is a reactive valve. This means that the valve will keep a consistent water temperature even if there is a drop in boiler supply water. A reactive valve of this kind can be used with intermittent, zone, or on-off controls.
A three-way tempering valve provides lots of benefits in a Type 2 situation. The valve does not cost too much, it does not need to be wired electrically, gives reactive service, is simple to install, and can give a huge variety of positions. However, a circulator has to be installed on the radiant side of the valve, to insure correct flow to the radiant system. A temperature gauge needs to be installed downstream of the MIX port, to enable the supply water temperature to be monitored.
From all of the choices accessible for making a boiler that does not condense with hot water baseboard system and radiant heat system, a three-way tempering valve is the cheapest and easiest to install.
Texas Heating and Cooling: Localized Heating Systems
Localized home heating systems have been available for a long time. Despite these systems being primarily used to warm people’s homes, they also have an aesthetic appeal and add to the decor to the home. The construction of a localized fire place requires a lot of attention to detail due to the fact that poor construction can lead to the emission of fumes to the interior of the house, which would make the house stuffy and congested. Fire places in the home serve as a great compliment to the home and a welcome addition to the living room.
Development of central heating systems
The development of the heating systems started after the second world war, where new buildings were constructed with heating systems in place. These involved installation of a heating system such as a boiler that was powered by either coal or petroleum fuel such as diesel or gas. These systems heat and circulate hot water through pipes, thus warming the internal atmosphere. Other systems operated by pumping hot air into the rooms. Both require various amounts of pipes being installed within the home, many of these pipes where installed on the outsides of the walls, which led to many people burning themselves. As power drills and power tool accessories became more advanced, drilling through walls became an easier task. These systems come in a wide range of applications with the current ones using a diesel boiler to boil water which is circulated throughout the building. Other areas use district heating systems whereby ultra-heated steam is generated by a central body and is circulated to the residential homes. Another form has been the solar powered heating systems, that utilize sun energy to heat water which is then circulated throughout the house, thereby warming the house.
Apart from the need to warm the house, cooling and air conditioning of the home is also very important in order to maintain a comfortable internal environment. Various cooling and air conditioning systems have been developed which operate by a moderate refrigeration process, whereby air from the room is passed through a cold surface which absorbs the heat from the air thus cooling it down. These cooling systems have advanced with time, with the current systems being designed to cool the homes naturally without using air conditioner.
Localized home warming solutions
Localized home warming systems provide a good solution to house warming especially where there is a need to manage the energy use bills as well as to provide a friendly atmosphere in the living room. They are usually constructed based on the size of the room to be heated and provide a great source of warmth and energy efficiency. Texas fireplaces offers a wide variety of fire place systems designed to offer the most unique decor to the living room as well as warming the room. They come in various sizes and designs and can be custom built to the design of the house. Fire place systems allow for energy saving because the combustion process can be regulated by closing the vents and the door when they are not in use. This slows the combustion process which can be reactivated on opening the vents.
