Harrison to make return to ring

first_imgAudley Harrison is to return to boxing in a 10-rounder against Chelsea’s Ali Adams in Brentwood on 14 April.It will be the Wembley heavyweight’s first fight since losing a one-sided world title clash with David Haye in November 2010.Harrison, 40, was crowned Olympic champion in 2000 but has been much maligned during his professional career, and the third-round stoppage by Haye was his fifth defeat.“Anyone can lose but I didn’t lose with dignity. I was never going to retire after that performance,” said Harrison.“I’ll have too much for Ali Adams. I intend to show I still have a future in the game.”Adams, who was born in Iraq, is 10 years younger than Harrison and has a record of 13-3-1.Follow West London Sport on TwitterFind us on Facebooklast_img

Raiders’ future rests with Gruden’s ability to assemble a roster

first_imgThe Ravens are nobody’s pick to make the Super Bowl, … If Jon Gruden the CEO doesn’t do a better job, then Jon Gruden the head coach has no chance.That’s the state of the Raiders with five games left in the season after absorbing a 34-17 road loss to the Baltimore Ravens in which the talent disparity was glaring in a league designed to reward parity and provide as much competition for the consumer as possible.

Using a Tankless Water Heater for Space Heat

first_imgYou can buy a gas-fired tankless water heater for $600 — or even $300, if you want a bare-bones model. These appliances are remarkable: they are compact enough to hang on a wall and can begin producing an “endless” flow of hot water almost instantly. Many people look at these small appliances and think, “Why can’t I use one to heat my house?”The answer is, you can. However, just because you can, doesn’t mean you should.It’s true that a tankless water heater can easily heat most single-family homes. It’s also true that a tankless water heater is smaller and less expensive than a boiler or a furnace. So what’s the catch?There are several catches, and the issue is fairly complex. The basic problem is that tankless water heaters need a high firing rate — as high as 180,000 BTU/h — to quickly bring cold tap water up to 120°F or 140°F. These appliances work best when the incoming water temperature is relatively low (below 85°F). On the other hand, a space heating appliance for a single-family home or apartment needs a much lower firing rate — usually between 10,000 BTU/h and 20,000 BTU/h — and must be able to tolerate incoming water temperatures that are higher than the temperature of cold tap water.Trying to use an appliance designed for the instantaneous production of domestic hot water for space heating is possible, but doing so requires the system designer to accept certain compromises and to engage in several contortions.Before we can analyze the advantages and disadvantages of using a tankless water for space heating, we need to discuss three questions:Systems that use a single heating appliance for both space heating and domestic hot water are called combi-systems (or combo-systems).In theory, a tankless water heater can be… This article is only available to GBA Prime Members Sign up for a free trial and get instant access to this article as well as GBA’s complete library of premium articles and construction details.center_img Start Free Trial Already a member?
