Help!!! [Don’t want to burn the house down.]
Q: Hi all very simply it’s copper tubes, small pc fans, and surrounding the copper tubes is several 15 to 20w quartz halogen (I think?) heater spotlight lamp bulbs. If this is placed in a wall to heat a small bathroom bringing cold air outside in, will it be able to do so? Thanks a bunch – any recommendations for efficiency or a similar design welcome. – A1d4n_18
A: Sounds pretty good to burn your house down. How is this cheaper than something UL approved?
You’ll also not be anywhere near the same efficiency as something off the shelf. Don’t do it.
This. Pick up a wall can at the local big box home improvement warehouse for $100-200. It’ll not be a fire hazard AND it recycles warm air from the room, not cold outside air.
Service Recommendations for Post Irma and Harvey Flooded A/C Units
by James Bowman, National Technical Manager–HVACR, RectorSeal, LLC.
The wake of Hurricane Irma and Harvey left thousands of residential air conditioning systems flooded throughout regions of Florida, Georgia and southern Texas and Louisiana.
Now, hundreds of HVAC service companies are facing decisions of restoring or replacing those air conditioning units. Not all properties have flood insurance. Therefore, many property owners are faced with prioritizing repairs on a very limited budget or even through charity and government assistance.
Flooded A/C units don’t always mean replacement, because there are various degrees of damage. If a service tech has a chance to save a mildly-damaged unit or simply replace a component, it might be a tremendous benefit for a flood-ravaged homeowner already facing tens of thousands of dollars in other residential construction material replacement costs. A quick fix with the strategy of later replacing the unit could also be beneficial to homeowners attempting expedite the drying out a flooded home’s interiors.
Therefore, the following is a service tech guide with tips for determining whether or not to salvage a flooded unit. Obviously, the floodwaters must have receded, power must be restored to the home, and all electric to the unit shut off.
I’m 18 years old and going into my fourth week of college for HVAC. So far we have talked about states, matter, the components of refrigeration, OHSA etc. I am understanding all of that slowly, I still have some trouble with it but I’m slowly absorbing it.
However, when my professors talk about BTUs, I am at a loss. I understand that it is a way to calculate heat and that it stands for British Thermal Units but that’s all I can understand. When I try to read my textbook about it, I get confused because it goes so in depth.
Can someone please help me? – NostalgicDuck
The simplest explanation is the definition. It’s the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. – Zackhood
So if I had a pound of water sitting at 70° F, if the temperature was raised to 75° F that would be 5 BTUs? – NostalgicDuck
I think he got it. By jove he got it! – toomuchpork
