Think I'll opt for a stainless hx then. The boiler being replaced is at least ten years old and I'd hope the next one lasts longer rather than shorter. Now that latent heat's being extracted from the flue gas and most boilers are modulating I'd say there's not much further to go efficiency-wise so longevity is something to aim for. Thanks Jim

If you’ve just discovered that it’d be more cost effective to completely replace your furnace versus just replacing the heat exchanger, you’re probably thinking, “Great. Well, the cost to install a gas furnace in the Denver area typically costs anywhere from $4,500 to $12,000.
Aug 13, 2018 · How much energy the heat exchanger extracts from the flue gas is referred to as the boiler’s Annualized Fuel Utilization Efficiency (AFUE) rating, and is often times described as an efficiency percentage. For example, a 30-year old boiler might be 70% efficient, meaning that for every dollar you spend on gas, 30 cents of heat escapes through
benefits of stainless steel heat exchangers Careful consideration of the heat exchanger material can have a significant impact on the overall running costs. Furthermore, commissioning should not be a one-off activity and should instead take a holistic approach over many years in order to optimise efficiencies.

Aug 23, 2011 · Hi. I am replacing a very old boiler, and have pretty much decided on either a Vaillant ecoTEC plus 418 or a Worcester Greenstar 18Ri. From the specs I see that the Worcester has an aluminium heat exchanger and the Vaillant has stainless steel.
However, the contractors that we have called for estimates say that we should get another cast iron boiler with efficiency of 80% and a life expectency of 30+ years instead of a stainless steel or aluminum high efficiency boiler because those last only 10-12 years and cost at least $3,000 more.

A gas furnace’s efficiency rating can primarily be determined by two factors: its AFUE rating (Annual Fuel Utilization Efficiency), which indicates what percentage of each dollar of natural gas purchased is actually used to heat your home; and the type of blower used in the furnace.
Furnace heat exchangers transfer heat from the burning fuel (typically LP gas, natural gas, or heating oil) into building air. In most designs combustion gases pass from the combustion source (oil or gas flame and combustion chamber) through the heat exchanger's interior tubing to an exhaust point
Pros: Stainless steel is the only material of the three that can be used in condensing boilers. These boilers capture additional heat by condensing the moisture in exhaust gases to be ultra-efficient. The problem is that flu gas condensate is very acidic and quickly destroys cast iron and aluminum heat exchangers.
Aluminized steel is cheaper than stainless steel. The stainless steel is stronger. It is more durable than aluminized steel. In respect to rusting, stainless steel does not rust. Aluminized steel can get corroded if the aluminum coat gets broken or overheated. Stainless steel heat chambers usually come with longer warranties.
Stainless steel heat exchanger every time, All modern boiler are condensing this means that condensate runs through the heat exchanger and is then taken away via a plastic pipe, you have to use plastic as condensate is mildy acedic meaning that it will attack metal, it will start to dissolve aluminium form the first day that the boiler is switched on, stainless steel is much more able to combat the action of condensate, also you will get "galvanic" action within a central heating system this
