Kitchen exhaust fans

All kitchens should have exhaust fans, a lot of hood fans do not vent the bad air to the out side, but instead they push the air through a charcoal filter and than exhausted it back into the kitchen. When these hood fans are used over 50 hours of use the charcoal filters should be changed. If you don’t, are your doing is blowing the smoke and cooking smells into the rest of the house.

Using an exhaust fan below 300 Cubic feet per minute, most houses have areas that leak this much air into these houses. Newer homes leak about 150 cfm around windows and doors.
If an exhaust fan is turned on blowing out 300 cfm, your short 150 cfm and it will draw it from a bad source. One of the easiest places for the air to come into the house is by sucking the air out of the chimney either the fireplace or the furnace chimney.

We remodeled a house along with the kitchen; we installed a 1280 CFM exhaust fan. We told the homeowner that he need makeup air he refused Than came thanksgiving, the family was there the owner has a 5’ wide and 4 tall open wood fireplace the fire was going for about an hour when the wife turned on the kitchen fan. Instantly the fireplace chimney reversed bringing the smoke into the house the fire in the fireplace was still burning but the flames were blowing horizontally into the room. He wanted a quick fix so he had a 12” fresh air intake installed into the cold air return on his furnace. This did fix 1 problem the fireplace now works properly while the kitchen fan runs on full speed.

If the furnace is running it was not sided to handle super cold air coming into the heat exchanger. With this much cold air coming into the furnace, the furnace cannot heat the house because now it has to heat the incoming cold fresh air. The other problem is that the heat exchanger is being stressed with 400 ° on the burner side and -10° on the other side this shortens the life of the heat exchanger by years.
If the house is warm because of the fireplace the furnace won’t turn on. With the fresh air dumping in to the return air plenum, the super cold air is now coming out all the vents cooling down your floors making a draft along the floor to the fireplace and the kitchen stove.
The proper way is to bring fresh air into the house and run it through a furnace designed to temper the makeup air.

Kitchen ceilings

When your looking at types of ceiling finishes in the kitchen. There are things you must thing about.
1. Are you using your kitchen as a showcase? Be careful what you choice.
2. Are you cooking a lot with grease? If you cook with a lot of grease at high temperatures grease evaporates and bond to a cooler Surface IE the ceiling.
Having a textured ceiling in the kitchen is a headache you cannot wash the ceiling. The only thing you can do is paint the ceiling and rolling paint on the texture comes off on the roller making a mess and to paint and clean up. Using a flat surface in the kitchen is an easy ceiling to maintain both in keeping it clean, or repainting the ceiling. If you are looking for a different type of look you can always use a knock down look not a easy to clean but very easy to repaint when you need to.
In some architectural designs wood ceiling looks good if the wood is finished either with paint of varnish finish. Unfinished ceiling are bad because dust cobwebs and grease bonds to the unfinished and is hard to clean.
They make a steel panel ceiling. This is a great ceiling because you can clean this type of ceiling.
A cool looking ceiling is a glazed ceiling 3 or 4 tones of paint in the same color family with a clear coat covering it. Again this type of ceiling is easy to clean.

Kitchen Windows

When designing a kitchen what should you be looking for when choosing a new window(s) in the kitchen?
There are 6 different types of windows available but only 5 can open. The picture window is just that a cased opening with a secured thermo pane glass installed in the opening.

Awning; With this type of window the operating devices are located at the bottom of the window that makes it easy to operate. These windows are hinged at the top and swing outward. The problem is that the kitchen countertop is 36” tall than the window is about 24-36” tall. IE the top of the window is between 5’to 6’ off the floor so when you are looking out the window at the sink all your eyes are looking at the top of the window jamb, you must duck to look out the window.

Glider; With this type of window the operating devices are located half way up the window that makes this window hard to operate when you lean over the sink and faucet.

Casement; This is a great type of window the operating devices are located at the bottom of the window that makes it easy to operate, also if the wind is coming from the left and you want to bring the air in open the right window and it will hook the wind and bring it into the kitchen.

Double Hung; This is a good looking window but it has a draw back you must on unlock the window, the lock is half way up the center of the window opening it from the bottom is adequate again the sink and faucet is the way.

Hopper; A hopper window is a cool design of a window but it swings and tilts into the room in the swing mode the window can not open the faucet is in the way.

Transom; Having a transom window over the regular kitchen window is great unless you have a ceiling under 9’ again the bottom of the transom and the top of the regular is in your line of sight.

What are the first questions you need to answer for a new kitchen

Where do I go for a new kitchen? Remember this 9tenths of the kitchen stores have no clue who you are or how you live or your unique physical abilities you have. They are there to get a fast sale and they’re on to the next customer. And you’re stuck with this kitchen for the 10-20 years. A high-end builder and /or remodeler should ask you these questions. To custom fit your kitchen to you and not having you do contortions in your kitchen went it’s time to cook something.

1. Who does the cooking? Who does the cleanup?
2. How is your eye sight? If your eye sight is poor you may need more lighting in the kitchen.
3. Is the cleanup person left or right handed? The placement of the dishwasher is vital for ease of loading and unloading dishes.
4. At what height do you like to work at tabletop height (30”) or counter top height (36”) workbench height (42”) or a height in between? Having improper work surface height is bad on your back, hips and legs. You may have a new kitchen, but hate to go into the kitchen not really knowing why.
5. What size is the family are you cooking for? This tells me what size the refrigerator has to be for breakfast. This also tells me what size cook top you will need.
6. How many different types of parties per year? Do you need a 2nd refrigerator for short-term storage? They make great under the counter refrigerators and freezer with pull out draws.
7. How much cooking do you do everyday? Every meal, or is there a lot of prepared foods, or do you eat out a lot? This tells me what volume of dishes you will be keep in the kitchen. IE if you cook a lot you will be baking cakes, pies and fancy items. This mean you will need a lot of preporation storage of mixer, food processor, etc., in easy reach of your work surface.
8. Now let’s look at your house and see the architecture of the home so we can match the
kitchen to the house. IE never put a modern kitchen in a house designed as an Amish or 1900’s bungalow home.
9. Are you going to feed the family in the kitchen or at a different area? If in the kitchen where?
10. How much square footage are you going to give to the kitchen area? If you need more can you take a little from another room or can we add on an addition.
