FORCED CIRCULATION SYSTEMS
Nowadays,.production.and.energy.savings.without.contaminating.the.environment.is.extremely.important..The.conven-
tional.energy.sources.of.the.planet.are.declining.to.a.threatening.level,.as.our.society.requires.an.increasing.amount.of.
energy;.as.a.result,.pollution.is.affecting.the.climate.balance.
On.the.other.hand,.the.Renewable.Energy.Sources.can.be.a.solution.for.both.the.energy.and.environmental.problem..The.
international.legislation.is.gradually.modifying.and.encouraging,.even.imposing,.the.use.of.alternative.energy.products.
with.the.aim.of.meeting.the.energy.requirement.without.placing.the.environment.at.risk.
DOMESTIC HOT WATER DEMAND
It.was.statistically.calculated.that.the.average.daily.consumption.of.a.family.varies.from.35-50.litres.per.person..Should.
we.add.the.consumption.of.the.washing.machine.and.dishwasher.in.case.they.were.connected.to.the.solar.system,.around.
20.litres.are.required.daily.for.each.appliance.(for.one.wash).
A.family.made.up.of.four.people.with.an.average.DHW.consumption.of.40.litres.per.person,.requires.a.160-litre.solar.
system...The.requirement.increases.by.at.least.40.litres.per.day.if.we.add.the.domestic.appliances.connected.to.the.solar.
system..To.obtain.the.maximum.benefit.from.the.solar.water.heater,.use.the.highest.amount.of.hot.water.possible.during.
the.day.so.that.the.plant.can.continuously.produce.during.the.sunny.period,.maintaining.yield.to.a.maximum.
GENERAL INSTALLATION RULES
Installation must be conform to the local standards in force for hydraulic and electric plants:.Remove.the.solar.system.
packaging. in. the. place. of. installation. to. protect. the. equipment. against. impacts. during. transport,. avoiding. resting. the.
collectors'.weight.on.the.pipes.connection.fittings..The.collectors'.crystals.must.remain.covered.until.installation.is.com-
pleted,.until.the.boiler.is.filled.with.domestic.water.to.avoid.the.filling.liquid.from.boiling.or.the.crystals.from.breaking..Do.
not.remove.the.plastic.protective.caps.of.the.connection.fittings.of.the.storage.tank.and.those.of.the.collectors.
Installation site: Before.installing.the.solar.system,.carefully.choose.the.place.of.installation.and.check.if.the.surface.
where.the.appliance.must.be.positioned.can.withstand.the.system's.weight.
Piping:.The.client.must.agree.the.path.of.the.pipes.and.cables.with.the.installer.in.order.to.ensure.correct.installation.
according.to.the.standards.in.force.concerning.electrical.and.hydraulic.systems.
Direction - Perfect inclination - Shading:. It. is. essential,. in. order. to. obtain. maximum. solar. system. yield,. to. properly.
choose.the.inclination.and.direction.with.regard.to.the.installation.place.and.the.maximum.production.period.requested.. .
The solar panels must be directed so that their surface faces the geographic South in the northern hemisphere (geo-
graphic North in the southern hemisphere), meaning they always face the equator. Deviations from the ideal orienta-
tion may reduce the system performance..
Correct.the.system.yield.if.the.change.of.the.correct.direction.is.inevitable,.by.increasing.the.collectors'.surface.based.
on.an.assessment.of.the.specific.conditions..As.the.angle.of.incidence.of.the.solar.radiation.changes.with.the.season.and.
with.the.system's.place.of.installation,.the.collectors'.angle.of.inclination.must.be.almost.equal.to.the.place.of.installation.
latitude..This.inclination.ensures.maximum.energy.production.on.an.annual.basis..To.ensure.full.exposure.of.the.collector.
surface.to.the.solar.radiation.during.midday.(at.least.4.hours),.it.is.important.to.prevent.the.system.from.being.shaded.
by.trees,.buildings.or.other.obstacles.
