Re: Tell Me What You Think
Mantus - Well, it looks nice but I'm afraid it won't function properly. The way a hot water coil is designed is to have the cool air come in from the bottom and the hot air leave from the top. It should be constructed so the air is drawn in at the lower side and the hot air is released at the upper side. Although this will function, it will not function at a good efficiency and may not heat the room adequately. To fix this without a lot of work would require you to put some slots or another grill in the top of the cover. The top of the box will become very warm and may warp because of heat differences of the top and bottom of the board. Sorry for the bad news. It does look good though.

Re: Tell Me What You ThinkQuote:
Looks good. I had a carpenter build one for me a while back and LEO is right about the function of the heat.My carpenter put screen on the inside of the grate so nothing would fall inside and the homeowner could just vacuum it.Also, he lined the inside of the box with a heavy duty foil paper(heat shield),I'm not sure how effective it was but I never got a callback.We also had a discussion about building it tight against the vanity,so it would'nt become a toothbrush trap.He had a little more room and left it about 3 inches away.But, you're workmanship looks right on!! Good luck, J |

Re: Tell Me What You Think
Hold the phone!!
You guys are comparing apples to oranges, I is a convector, the other is a raditor. two completely defferant types of heat, yes the raditors need some type of top opening. However convectors do not, the only thing needed to be done to the bathroom unit is provide airflow from below by means of a slice and or grate below the unit and the floor line. This will allow enough air flow thru the coil and exit thru the grate on the side/front. BJD |

Re: Tell Me What You ThinkQuote:
Holding phone. The convector has very specific needs to operate properly. There must be an in and an out separated by the aluminum fins/coil unit. If this is not done the heat output is much less than if you have the correct conditions. If you have a baseboard heater and you remove the front plate you will lose about 60% of its heating capabilities. This is the condition that must be upheld in order to have an efficient heat transfer. The radiator on the other hand, because of its size will overcome these deficiencies by brute force. However to keep it more effective you need to put a heat release (slot) in the top. With the price of fuel, efficiency is important.

Re: Tell Me What You ThinkQuote:
BJD, That is not always true! Cast iron radiators also heat by means of convection. The heat style in picture #1 is usually in a semi-recessed enclosure on an outside wall especially in a bathroom. The metal enclosure is a tighter fit than the wooden box shown and the metal(thin by design) does not retain heat like wood. I think more holes in this situation would be beneficial,since it is such a small piece of heat. In picture #2 that also could use more openings in the enclosure. When it comes to cast iron radiators having all sides and the top vented is very beneficial since they continue to heat(convect) long after the thermostat is satisified. Both gentleman did a nice job! Sometimes, it is a shame to see some cast iron radiators enclosed. There are some out there with really nice designed sections. J |

Re: Tell Me What You Think
Both boxes look good, very nice work guys. Minor point here - Air passing over a hot suface removes heat by convection. Both examples are convectors altho one of them is way more efficient due to more surface area. Because one looks like the radiator on your truck (which too is mis-named) doesn't mean it is. Radiators don't heat the air they heat surfaces by radiation, the sun is the best example, propane heaters etc. my nickels worth, Met.

Re: Tell Me What You ThinkQuote:
Just curious, are you making them so the heat is accessible for service? |

Re: Tell Me What You Think
I'm down south and don't do heat, we have plenty of that. Is there ever a fire hazard with these units?

Re: Tell Me What You ThinkQuote:
inspected is the boiler.Gas is inspected by a gas inspector and oil is done by the fire dept. The rest of the system, how big,how much heat and location is up the contractor to size properly.That's why air flow is so important,just like the vents on your'e AC. |
