Hot Water Recirculating Pump Problems

 · Hot Water in the Cold Pipe. If you turn on the cold water and get hit with hot water instead, you may actually have a problem with the bypass valve that's a part of your hot water recirculation system, rather than the pump itself. The valve is designed to close and keep the hot water in the pipes once it's up to temperature.

Hot air coming out of air intake/return vent? : HVAC

Brady, the return air that is producing hot air is closest to the unit in the attic than the other 2 return airs are. I'm not exactly sure about the fresh air damper/make-up air leading to the system. I did see a long metal pipe that went from the attic unit to the roof, but that looked more like an exhaust pipe.

Why Is My Furnace Running but Not Blowing Hot Air?

A dirty air filter affects more than just your home's air quality (though don't get us wrong, that's important). The humble air filter is at the root of many furnace problems. A clogged, dirty air filter blocks the return air flow to the furnace, meaning: There's less air to blow out of your vents.

Why Is The Air Conditioner Pipe Not Cold?

The air conditioner is conveying heat outside, therefore the pipe is really hot. The return pipe is warm because the heat exchanger outside can't wring all the heat out of it. There is no cold coming into your house: just fluid coming in that gets really hot, goes outside and cools down slightly. add a comment.

Temperature creep in hot water recirculation

 · The first hot water users in the morning can have overheated (creep) or underheated (droop) hot water when the system is not piped like we show in Caleffi idronics™ journal (Issue #11), Figure 7-5, or in the Installation Instructions for our 521, Series MixCal™ or Series LEGIOMIX® valves.

Return pipe is not hot on radiators and pipe into boiler

 · Return pipe is not hot on radiators and pipe into boiler. ... and the return is red hot by the lock shield but despite it only then travelling approx 7ft back to the boiler the return pipe is only warm to the touch. ... Bleeding the rads will only clear air from the rads, not the pipework.

Signs There's a Problem with Your Hot Water Recirculating

Hot Water in the Cold Pipe. If you turn on the cold water and get hit with hot water instead, you may actually have a problem with the bypass valve that's a part of your hot water recirculation system, rather than the pump itself. The valve is designed to close and keep the hot water in the pipes ….

Why is My Furnace Blowing Lukewarm Air?

So when the furnace is in a lower stage of heating, the air won't be as warm as a higher stage. The fix: Nothing. This is normal. You can check this by cranking your thermostat up a few more degrees to see if the air gets warmer. Air ducts are leaking. The lukewarm air coming out of your furnace can also be the result of leaky air ducts.

Why Is The Air Conditioner Pipe Not Cold?

How to Get Air out of Baseboard Heating Pipes

 · The air in the pipes doesn't pose a significant risk, but it can cause the pipes to emit loud noises as hot water circulates through them to heat the house. Eliminating that annoying noise is crucial to getting the full benefit and enjoyment out of a hydronic heating system. In this blog post, we will provide tips that homeowners can use to.

Radiators Are Still Hot When The Heating is Off, Why

 · When a diverter fails or gets blocked with debris, hot water intended for the hot water circuit can get into the radiator circuit. Then the radiators will be hot even though the heat is turned off. You do not have to live with constantly hot radiators. Your radiator service person will perform a drain-down and replace the faulty component.

Hot Liquid Line on AC

 · The air temperature going into the return could actually be much colder than the air temperature entering the evaporator coil due to air leakage of the return duct system. I find this condition in approximately 60% of the homes I inspect. 90% have air leakage, but 60% of them are significant enough to significantly cause adverse comfort.

Return

 · In homes with a single central return-air grille, return air often struggles to find its way back to the furnace.The result: room-to-room pressure imbalances that lead to uneven room temperatures, comfort complaints, higher energy costs, and even moisture problems in walls and ceilings. When a furnace comes on, heated air is pushed through supply ducts to registers in each heated ….

Heat recovery ventilation

Heat recovery ventilation (HRV), also known as mechanical ventilation heat recovery (MVHR), is an energy recovery ventilation system which works between two sources at different temperatures. Heat recovery is a method which is increasingly used to reduce the heating and cooling demands (and thus energy costs) of buildings.

The Air Return Size for a Furnace

A furnace return system must collect all the air being put out by that system. If the furnace is putting out 1,000 cubic feet per minute of air flow, the return system must collect 1,000 cubic feet and take it back to the unit. An insufficient return system or one too large will reduce the efficiency of the heating and increase energy bills.

Here are seven of the basic rules for getting your ducts

 · Basic Rule No. 1: Hot air rises, cold air falls. Ducts should be installed to take maximum advantage of natural air movement. For instance, for air conditioning to work properly, air returns, the.

Heat Pump Not Blowing Hot Air? Here's Why.

Here's why: The average body temperature is around 98.6 °F. And, in cold weather, heat pumps tend to blow warm air out at 95°F. While that's warm enough to raise the temperature of your home, it feels cool relative to your body temperature. This is different from a furnace, which can blast hot air over 100°F.

What is an Air Return Duct? (with pictures)

 · Mary Lougee Date: February 06, An air return duct is an important part of most HVAC systems.. An air return duct is basically a concealed air passageway in a home or other building that acts as a channel for pumping air out of an enclosed room and into the air conditioning or central heating system. These ducts typically start with vent grates in the wall, on the ceiling, or in the floor.

Hot Water Circulation Return Pipe

A return circulation pipe is sometimes provided in a hot-water system where it is desirable to have hot water available continuously at the fixtures. Typically for systems where the distance from the hot water heater to the consumption fixtures exceeds 25

 · A cold-air return is a vent that sucks cold air into a furnace so that it can be heated and brought back to a room through a furnace register. These vents are seen in many types of furnace systems, although there are alternatives, such as drawing air from the outside or from the area around the furnace. Depending on the design, each room in a.

Why Is The Air Conditioner Pipe Not Cold?

The air conditioner is conveying heat outside, therefore the pipe is really hot. The return pipe is warm because the heat exchanger outside can't wring all the heat out of it. There is no cold coming into your house: just fluid coming in that gets really hot, goes outside and cools down slightly. add a comment.

Hot Blast Stove Question M

 · Instead of using 2-8" duct pipes, we used a "T" and made the 2 duct pipes come together in the "T" and out into one 8" pipe into the return of the gas furnace duct. I am wondering if going 2 into 1 on this wood furnace if that would be restricting air flow in the house. Cold air return is installed and drawing nice as is everything else.

Radiator Valves

 · It depends on how the radiator was piped when it was installed. The pipe which brings water from the boiler to the radiator is called the Flow. The pipe which takes it back to the boiler to be re-heated is called the Return. So, starting the system from cold, the Flow pipe is the pipe which gets hot ….
